"I was really happy with my two goals and it was important for us to get three points against a difficult West Ham side," said the French international.
"The most important thing was to get a victory and keep fighting with Manchester United for second place.
"It is always good when you play two games in such a short space of time and you can come away with a victory. I think it is a good advantage for us.
"It is nice for me to get these goals with the FA Cup final just a couple of weeks away.
"I really enjoyed being back in the team and I am determined to do my best when I have the chance to play. I am delighted I managed to score two goals."
