Chelsea icon Marcel Desailly has slated the club's current midfield. Desailly says the engineroom needs a complete overhaul this summer.
He told the Mirror: "First of all they need to get rid of four or five guys who are not Chelsea players.
"I think five players have to leave the club. After that it depends on the finances.
"Previously the midfield was absolutely amazing. Even if they weren't winning the Premier League, it was holding the team. The midfield was playing well.
"Now Joe Cole is not expressing himself as he wanted, Ballack has disappeared the last two months, Mikel is playing his best, but the team misses Essien. So this is why the defence is suffering."
