Xabi Alonso’s Chelsea rebuild is officially underway — and the summer of 2026 at Stamford Bridge is shaping up to be one of the most ambitious and strategically coherent transfer campaigns in the club’s recent history. Three significant stories have emerged on Saturday June 27: Chelsea are interested in signing Sunderland’s Granit Xhaka for a reunion with the manager who oversaw his greatest-ever club season; Marco Palestra has undergone his Chelsea medical after arriving from Rome to finalise a £43m deal from Atalanta; and Chelsea have enquired about Crystal Palace centre-back Maxence Lacroix as Alonso continues his defensive overhaul.
For Chelsea supporters watching a manager with genuine world-class pedigree begin his first summer transfer window at the helm, these moves paint the picture of a head coach who knows exactly the type of player and the squad culture he wants to build. Here is the complete breakdown of every Chelsea transfer development.
🔵 Chelsea Summer 2026 Transfer Activity — At a Glance
- Granit Xhaka (Sunderland): Chelsea interested — no club-to-club contact yet; Sunderland not willing to sell
- Marco Palestra (Atalanta): £43m deal — medical completed Friday; Alonso’s first signing as Chelsea manager
- Maxence Lacroix (Crystal Palace): Chelsea enquiry made — one of several centre-back targets for Alonso
- Trevoh Chalobah (Chelsea): Como interested — deal looks difficult; other clubs also circling
- Xabi Alonso: Starts work at Chelsea next week
Granit Xhaka: Chelsea Explore Sunderland Midfielder for Reunion With Xabi Alonso
The most intriguing Chelsea transfer story of the weekend involves a player who spent the final day of last season beating them. Chelsea are interested in signing Granit Xhaka from Sunderland — the Swiss midfielder who played a pivotal role in the Black Cats’ remarkable 2025/26 campaign, most memorably helping secure Sunderland’s Europa League qualification by defeating Chelsea on the final Premier League matchday.
The story is defined by one compelling relationship: Xhaka and Xabi Alonso worked together at Bayer Leverkusen, where the Swiss captain was one of the fundamental pillars of the German side’s historic unbeaten Bundesliga title season. Alonso — who arrived at Chelsea with an explicit mandate to inject winning culture, tactical intelligence, and Premier League experience into a squad with an average age of just 23.8 years — sees Xhaka as a specific profile of player that his young group critically needs.
The midfielder brings exactly what Alonso’s system demands: a combative, technically assured defensive midfielder capable of setting tempo, protecting the backline, and providing the positional discipline that allows younger, more attacking players to express themselves. At Leverkusen, Xhaka was the heartbeat of Alonso’s press — the player who made the team’s structure function. The logic of reuniting them at Stamford Bridge is tactically coherent and immediately legible.
What did Xhaka achieve at Sunderland in his first Premier League season?
Granit Xhaka joined Sunderland from Bayer Leverkusen for £13m in the summer of 2025 and delivered a season that exceeded every expectation. He made 34 Premier League appearances, scored one goal, and provided six assists — but his most significant contribution was the structural stability and leadership he provided to a Sunderland side that not only survived in the Premier League but secured Europa League qualification on the final day of the season. The Black Cats’ defeat of Chelsea in that climactic fixture now adds an additional layer of irony to this particular transfer saga.
Why Sunderland Will Fight to Keep Xhaka — and Why Chelsea Won’t Pay Over the Odds
This transfer saga is complicated by two equally firm positions on opposite sides of the negotiating table — and both are entirely understandable.
Sunderland’s position is unequivocal: Xhaka is not for sale. As of Saturday June 27, there has been no club-to-club contact, and the Black Cats are unwilling to entertain offers for their most important midfield asset. Xhaka was central to everything they achieved last season — his experience, composure, and ability to manage the tempo of matches against top-flight opposition was the factor that transformed a newly promoted side into a legitimate Europa League contender. Losing him would fundamentally undermine the competitive identity Sunderland have spent two summers carefully constructing.
Chelsea’s position is equally considered. Xhaka turns 34 in September — and the club have made clear they would not pay over the odds for a player entering the final significant phase of his career. The financial parameters of any deal would need to reflect both the realities of his age profile and the fact that his Sunderland contract value — set at the time of his £13m arrival from Leverkusen — does not reflect the inflated demands of the top-six transfer market.
The Xhaka situation also carries a personal dimension. When Xhaka left Leverkusen last summer, London was already his preference — with West Ham having been a genuine option before he ultimately chose Sunderland. Whether that desire to return to the capital remains as strong now that he has settled in the north-east and helped build something meaningful at the Stadium of Light will be a decisive factor in how this saga develops.
Marco Palestra Completes Chelsea Medical: Alonso’s First Signing Arrives From Atalanta at £43m
While the Xhaka story remains in exploratory territory, one Chelsea summer deal has already moved to its conclusion. Marco Palestra underwent his Chelsea medical on Friday after arriving in London from Rome on Thursday evening to finalise a £43m transfer from Atalanta — making the 21-year-old Italian right-sided defender Xabi Alonso’s first signing as Chelsea manager.
Palestra’s arrival at Stamford Bridge is a statement of clear tactical intent. The Italian has been described by analysts as one of Serie A’s finest defensive performers of the 2025/26 season — a technically polished, physically dynamic right-sided operator capable of functioning as either a traditional full-back or a wing-back within Alonso’s fluid attacking system.
The wing-back dimension is particularly significant. Alonso’s Leverkusen side operated a 3-4-2-1 or 3-4-3 system in which the wing-backs were central to both defensive compactness and attacking width creation — roles that required players combining elite defensive positioning with the athleticism and delivery quality to contribute consistently in the final third. Palestra fits that specification precisely — and at 21, his development arc suggests significant further improvement under Alonso’s meticulous coaching approach.
Who is Marco Palestra and why did Chelsea sign him?
Marco Palestra is a 21-year-old Italian right-sided defender from Atalanta who has established himself as one of Serie A’s most accomplished defensive performers in the 2025/26 season. Chelsea are signing him for £43m as Xabi Alonso’s first transfer at the club. His ability to operate as both a right-back and right wing-back makes him ideal for the flexible positional system Alonso is expected to implement at Stamford Bridge — the same system that delivered Leverkusen’s unbeaten Bundesliga title.
Maxence Lacroix Enquiry: Chelsea’s Centre-Back Search Targets Crystal Palace Defender
The third significant Chelsea transfer development of the weekend involves their central defensive rebuild — an area that Alonso has identified as a fundamental priority of his first summer window. Chelsea have made an enquiry about Crystal Palace centre-back Maxence Lacroix, the 25-year-old French defender who impressed significantly in the Eagles’ defence last season.
Lacroix is described as one of several centre-back targets that Alonso and Chelsea’s sporting department are assessing — a position they are approaching with the thoroughness that a long-term structural decision demands. The French defender combines physical power, aerial dominance, and the technical composure on the ball that Alonso’s possession-based system requires from its centre-back pairing.
Whether Crystal Palace are willing sellers — and at what price — will be the primary question to emerge from Chelsea’s initial enquiry. Palace’s own summer recruitment will influence their appetite for departures, and Lacroix’s value in the current market suggests any deal would require a fee in the £35-45m range to begin serious conversations.
Trevoh Chalobah: Como Interest as Chelsea Reshape Their Defensive Squad
On the outgoing side of Chelsea’s defensive restructuring, Italian club Como have emerged as interested parties for centre-back Trevoh Chalobah. The Chelsea-developed 26-year-old has been on the periphery of the first-team setup in recent seasons — and with Alonso’s arrival bringing new defensive priorities and targets, a summer exit has become increasingly plausible.
However, the deal appears far from straightforward. Sources indicate that a Como acquisition looks difficult to achieve, primarily because of the financial gap between what the Italian club can offer and what Chelsea would require to sanction a permanent departure. Other clubs are understood to be monitoring Chalobah’s situation, suggesting that if Como cannot bridge the gap, an alternative buyer may emerge before the window closes.
Xabi Alonso’s Blueprint: What Chelsea’s Summer Rebuild Tells Us About His Vision
Taken together, the emerging transfer activity under Alonso tells a coherent story about the specific profile of club he is attempting to build at Stamford Bridge. The strategic logic across the three primary moves is immediately legible:
- Palestra at right wing-back: Confirms the fluid 3-4-3 / 3-4-2-1 system Alonso deployed so successfully at Leverkusen — wide defenders who can function as attackers are the structural engine of his pressing system
- Xhaka as midfield anchor: Alonso needs his version of a “quarterback” midfielder — a player who controls tempo, protects space, and provides the positional discipline that allows Chelsea’s younger attacking talent to take risks. Xhaka is that player, having performed the role for Alonso for three seasons
- Lacroix at centre-back: A technically assured, physically dominant centre-back who can play out from the back under pressure — the Alonso system requires defenders who are comfortable as ball-players, not merely defensive stoppers
Alonso begins work at Chelsea next week — and with Palestra already through his medical, the pace of the rebuild is set to accelerate dramatically through July. Chelsea’s average squad age of 23.8 years means the experienced players Alonso is targeting — Xhaka, Lacroix, and potentially others — will be arriving specifically to provide the winning mentality and tactical intelligence that elite youth cannot generate on its own.

Maxence Lacroix is a 25-year-old French centre-back currently at Crystal Palace. Chelsea have made an initial enquiry about signing him as part of Xabi Alonso’s defensive rebuild. Lacroix is one of several centre-back targets the club are assessing, combining physical power and technical composure on the ball that suits Alonso’s possession-based system.
What happened to Trevoh Chalobah at Chelsea?
Trevoh Chalobah is expected to leave Chelsea this summer, with Italian club Como among the interested parties. However, a Como deal is described as difficult to achieve due to financial gaps, and other clubs are also monitoring the 26-year-old centre-back’s situation. His departure would form part of Chelsea’s wider defensive squad restructuring under Xabi Alonso.
What system will Xabi Alonso use at Chelsea?
Based on his Chelsea transfer activity, Alonso is expected to deploy a 3-4-2-1 or 3-4-3 formation at Stamford Bridge — the same fluid system he used to deliver Leverkusen’s unbeaten Bundesliga title. The signings of Palestra (right wing-back profile), the interest in Xhaka (midfield anchor), and the search for a technically assured centre-back all align precisely with the structural requirements of that system.
