Ray Wilkins has backed Chelsea manager Carlo Ancelotti to turn around the club's torrid season.
Chelsea have gone into freefall since Wilkins was sacked as assistant coach two months ago, slipping from Premier League leaders to fifth place, nine points behind Manchester United.
Wilkins puts Didier Drogba's loss of form down to his bout of malaria, but admits other players have shown a mystifying lack of belief.
Wilkins said: "When I watch them play there's a lack of confidence there from a few of the players that shouldn't really be the case because they are top quality players, and I'm sure they will get back to the standards that they have performed at.
"It's been very disappointing. If you look at the level of performance it certainly hasn't been there and when you have a number of world-class players not actually playing to their maximum it's magnified 10 fold."
