Barcelona midfielder Sergio Busquets has said that it is important his team make as few mistakes as possible in their Champions League match against Bayern Munich this evening.

The two teams will meet at Camp Nou in the first leg of their semi-final tie, and Busquets admits that getting a positive result is all that matters.

"All the best teams in Europe are involved," he told UEFA.com "Here in Spain, in the Liga, the teams are maybe more technical, but I think the Champions League is more difficult, more physical.

"After the group stage you have the knockout rounds, where a single goal really can punish you. In the league there is more margin for error; it's just about getting the three points and the result doesn't matter."

Barcelona were beaten 7-0 on aggregate by Bayern when the teams played in the last four two years ago.
