Costa: I need to prove myself

Chelsea striker Diego Costa admits he is relishing the chance to prove himself to the fans against Real Sociedad this evening.

Costa, who will be introduced to the Stamford Bridge faithful prior to the match, admits moving to the Premier League was 'an easy decision'.

"I hope my actions on the pitch and my feet will do the talking and then people can decide if I'm a good player or not," he said.

\"All I can say is I love playing hard and fairly. I want to improve, not only as a player but as an individual, and I believe this is the perfect place for me to do that.

"Joining was an easy decision for me. We have some of the best players in the world, the best manager in the world and it's a club with great history.\"

Costa was part of the Atletico team which ended Chelsea's interest at the semi-final stage of the Champions League last season, an evening he recalls with great fondness.

"I remember the atmosphere and the passion of the supporters," he said. "They stayed right until the end, getting behind their team, even though it was unlikely they could win after we scored two quick goals.\"
