Alves looks to improve

Barcelona defender Dani Alves admits his side still need to sharpen up in Europe despite moving to the top of their Champions League group with a 2-0 win over Dynamo Kiev.

With Rubin Kazan holding Inter Milan earlier in the evening, holders Barca took control of Group F after seeing off Dynamo at the Nou Camp thanks to goals in either half from Lionel Messi and substitute Pedro Rodriguez.
