The striker could make his Champions League debut tomorrow.
"I told the manager if I stayed I would keep fighting for the club. Now it's about the next months and years with Chelsea," he said this morning.
"This is part of football. It didn't happen. I'm a good professional and always work hard. I will keep doing the same.
"I want to play. It all depends on me and the performance I put in on the pitch. If I don't perform, it will be only my fault.
"I know I haven't played as good as when I was in Newcastle or West Ham, but I needed time to settle. I keep working hard and believe the reward is behind the work."
