Former Chelsea star Marcel Desailly has urged the west London club to sign on quality players as back up for Nigerian winger Victor Moses.
Desailly said there is the need to beef up the side ahead of the new season.
The former Blues defender told the Daily Mail: “What was working last season with Antonio Conte cannot suddenly not work this season.
“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.”
