Ricardo Carvalho was pleased with his playing return for Chelsea.
The veteran defender featured in the defeat to Eintracht Frankfurt.
Asked afterwards how he was feeling, Carvalho told chelseafc.com: "Good, it has been a hard week with double sessions every day, so it is normal to feel a bit more tired than usual but we are getting fit.
"I think we could play much better but the pitch was a little bit difficult, you could feel it during the game, and we made a mistake with the penalty and they scored, so I think we should have had a draw at least."
