Former Chelsea captain Marcel Desailly has urged Chelsea owner Roman Abramovich to overhaul the squad in the summer instead of sacking Antonio Conte.
Chelsea have struggled this season under Conte and various reports claim the Italian is set to leave Stamford Bridge at the end of the season.
“What was working last season with Conte cannot suddenly not work this season,” Desailly told Daily Mail.
“Before they’ve changed the coach, and kept the players. This time they should keep the coach and look to move four to five players on.
“Your best players’ performances have dropped and Chelsea did not get the correct players with the correct strengths or another top player in the summer.
“Players like [Victor] Moses and [Marcos] Alonso played a magnificent season last year but they were in need of support this year.
“It’s been a collective failure at Chelsea this season. I don’t think the situation that Chelsea are in is Conte’s fault – you must give him that season.”
Desailly believes Chelsea have struggled this season because of the sales of Diego Costa and Nemanja Matic.
“Massive. Massive,” Desailly said when asked about the impact of the sales of Costa and Matic in the summer.
“Costa would have scored 10 goals more than [his replacement] Alvaro Morata. So maybe that’s five more wins and that’s a big difference.
“And the system of three at the back did not work this season because Conte lost Matic.
“Matic fitted with N’Golo Kante at the time and Cesc Fabregas fitted better in that system with him too. Together they protected the defence like it was needed.”
