Barcelona boss Pep Guardiola remained upbeat after losing the first-leg of their Champions League tie to Arsenal.

David Villa's goal in the first half was cancelled out by Robin Van Persie and Andrey Arshavin strikes late in the second session.

Guardiola said: "It was a fantastic game. Arsenal are a great team but we still have the second leg," the coach told the English media after the game.

"We dominated and took control of the game. There were many chances for both sides and we created more opportunities than we did last season but this happens sometimes."
