"When we changed coach [and Roberto Di Matteo took over] it was a bit more similar [to Liverpool manager Rafael Benitez's style]. That had a good side to it, which was that I learned: I became a better player," he said.
"I can now do things that I was not able to before. You can be the player that your coach wants, but you're not the player that people expect you to be. I spoke to Steve Holland, the [Chelsea] assistant, a lot and we worked hard on it.
"I became more mature, I came to know myself better and became conscious of the fact that it depends on me.
"I learnt to be more self-critical, to understand everyone better and to accept the situation.
"I learnt that if we won it didn't matter that I hadn't played. I had to keep working.
"When I retire the only thing that concerns me is that no-one can say that I was a bad team-mate or disrespectful or self-important."
