Chelsea told why summer signing is struggling with Xabi Alonso tactics

Carragher says Lacroix looks uncomfortable in Alonso's system, struggling when Chelsea switch from three to four at the back.

Jamie Carragher has questioned Chelsea's summer signing Maxence Lacroix, suggesting the £52million defender from Crystal Palace is not suited to Xabi Alonso's tactical setup.

Carragher praised Lacroix's performances in a back three at Palace but believes he lacks the mobility and comfort required when Chelsea shift into a four-man defence. Speaking on Sky Sports' Overlap, Carragher highlighted specific struggles against Tottenham, where Lacroix appeared uncomfortable pressing man-to-man and jumping out to mark attacking players.

The analysis comes as Chelsea's defensive record remains a concern despite the investment. The Blues have conceded 18 goals in 10 games with just one clean sheet, against League One Luton Town in the Carabao Cup. Carragher suggested Chelsea's entire back line lacks a standout leader to build the defence around, describing the defenders as "average" across the board.
