Manchester United striker Carlos Tevez is convinced Chelsea are due to suffer a major drop in form over the Christmas period.

"I think they (Chelsea) are a great team," Tevez told Sky Sports News ahead of Saturday's home meeting with Sunderland.

"But I also think that as it is for me, at 24 years of age, it is sometimes very hard to recover and play Sunday and Wednesday.

"I would imagine that for some of the Chelsea guys that are much older it would be even harder.

"I think that the intensive Christmas schedule will take its toll on them because they have some great players but not so much strength in depth."
