Frank Leboeuf believes that Chelsea's recent results prove that they are over the hill.
The Blues have gone on a five-match winless streak that has threatened to derail their quest to successfully defend the league title, since the rough patch of form has seen Carlo Ancelotti's men plunge to fourth position in domestic circuit.
The former AC Milan boss had maintained that his side had come out of their slump in form after the draw with Tottenham Hotspur at White Hart Lane, but Leboeuf insists otherwise.
"I don't agree that the game at Tottenham was the turning point for their season,"
"It is hard for me to criticise my former club and I love them but I really feel they are at the end of the cycle.
"When I saw them flying at the top at the start of the season, I wondered if I knew anything about football any more but now we are seeing the truth and reality of that club and those players."
Leboeuf added: "They need to do something at the end of the season where they will need to sell and buy players.
"Of course, they didn't have a bad game against Spurs but one or two years ago that match would have been won by Chelsea.
"I really feel Chelsea is not Chelsea any more. I am sad about that. We need a new Chelsea for next season."
And with a blockbuster showdown with Manchester United looming large on the horizon, the Frenchman hopes he is wrong in his assessment of the west London outfit.
"Of course, I hope I will be wrong," said Leboeuf. "The vertical column of John Terry, Michael Essien, [Frank] Lampard and [Didier] Drogba are back and that's important but it will be a tough game against United.
"They have to win and then at least draw against Arsenal if they want to keep surviving in the competition. The positive thing I can say about Chelsea is that they haven't had any luck."
