Frank Leboeuf has written off Chelsea's championship chances and former centre-back partner Marcel Desailly has also cast doubt on their hopes of retaining the Barclays Premier League.
The Blues are currently on their longest winless streak in the league for a decade, having failed to record a victory for five matches, and slumping from top spot to fourth in the table. Desailly and Leboeuf marshalled the Chelsea defence the last time the club went on such a poor run, during the middle of which manager Gianluca Vialli was sacked.
"It is hard for me to criticise my former club but I said at the beginning of the season that I didn't think they would be winning the championship," said Leboeuf.
"I love them but I really feel they are at the end of the cycle.
"When I saw them flying at the top, 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. 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."
Desailly, who spent six years at at the club and played alongside Leboeuf both in their 2000 FA Cup triumph and France's 1998 World Cup final win, added: "When you look at the games at the beginning of the season, you thought, 'Wow, Chelsea are going to crush the Premier League from beginning to end'.
"It's been six weeks really where Chelsea have been awful. I am annoyed they haven't been able to bring in a top-class player who can improve the energy of the team.
"It looks like Chelsea want to bring their young players into the team but they have not had enough experience to hold the team together. I am not sure if Chelsea will be able to win the title but they will be around the top."
