Quite interesting stuff, especially saying that he'll be on the bench today and will probably get some minutes:

For me, I think that this first-year at Chelsea has been very good for me and my career. I have learned many good things as a player and I hope that next season can be as happy as this one. In the Premier League, Chelsea didn't have a good season. But, we are in the final of the Champions League and we won the FA Cup, so I think the club is very happy with the players who are playing in the first-team. Tomorrow, they will give me a chance to be on the bench and probably make my debut so, I am very at the club and I have no regrets about coming here. I will see what happens next season.
