The Brazilian admitted that he finds the sessions "boring" and a run of six games in 16 days means that he will spend less time at the Blues' Cobham training complex.
"I like to play games. I don't like to train, it's boring sometimes," the Daily Mail quotes him as saying.
"Personally for me [the fixture pile-up] is amazing. I love to play games, so if I had to play every day I would want to. You need to rest sometimes but I prefer to play games than training, for sure.
"I want to play. I want to be on the pitch. Sometimes I am tired, but when I'm on the bench I'm not tired. I love to play football."
The former Benfica man was signed for around £25m in January 2011.
