Right until the 95th minute we have to be united.”advertisementThe coach confirmed that Javier Mascherano would be back from injury for the game and said he was happy to have Sergio Busquets available after the defensive midfielder missed the first leg.”Getting (Busquets) back is always great news,” he said.”He is one of the most tactically intelligent players there is and a key man for us. The more he can do, the better for us.”Barcelona captain Andres Iniesta said the team needed to put in its best performance of the season.”We have to play a perfect match. We have to create the maximum number of chances and score goals. We probably need to play our best match of the season,” he said.
