The Barcelona frontman admits that the tie isn't over despite Barcelona securing a first leg 2-0 victory at the Madrid's Bernabeu stadium
A Lionel Messi brace put the Pep Guardiola's men into a commanding position going in to the second leg at the Nou Camp, however they were given a helping hand after Madrid defender Pepe was given his marching orders for a tackle on Dani Alves.
And speaking to www.as.com after the match, the Barca striker said: “I think we were far superior throughout the match. I think Madrid being reduced to ten men was crucial.
“It’s a red card and when you fail you have to pay”.However, Villa refused to agree that the tie was over and insisted he expected a challenging second leg.
"We have a tough game at home [in the return leg]," he added.
"For now, we must think about the league and get ready for a very tough ninety minutes.
“We won the first leg of the semi-finals. We played our way and this must be maintained.
“We opened the field a lot to them, they made it difficult but we had the players in midfield.
"Today we are happy.”
