Chelsea have pivoted their transfer strategy, now prioritizing a move for a centre-back with Crystal Palace's Maxence Lacroix emerging as the primary target. Discussions are also underway for Rayo Vallecano full-back Pep Chavarria, signaling a defensive overhaul at Stamford Bridge.

Meanwhile, Sunderland have rejected an £8 million bid from Chelsea for captain Granit Xhaka, a midfielder who previously played under Xabi Alonso at Bayer Leverkusen. The rejection underscores the complexity of Chelsea's squad rebuilding efforts this window.

The pursuit of Lacroix represents a rapid rise for the player, who progressed from Italy's third tier with Atalanta's under-23 side to a potential Premier League move within three years. His addition would address Chelsea's need for depth and physicality in central defense.

Should the club secure both Lacroix and Chavarria, it would signal a tactical shift—potentially deploying a back three formation. Such a system could maximize the strengths of existing personnel while integrating new arrivals.

However, sources suggest Chelsea may face competition for Lacroix, as multiple Premier League clubs monitor the French defender's situation at Selhurst Park. Financial fair play constraints may also limit the scale of their spending before the window closes.
