Barcelona coach Tito Vilanova hopes that midfielder Sergio Busquets can recover from his groin injury in time for their Champions League clash against Bayern Munich.

However, fellow midfielder Javier Mascherano has been completely ruled out of the semi-final second leg at Camp Nou on Wednesday.

"Sergio Busquets and some others are still suffering from minor injuries," Vilanova told reporters on Tuesday. "We will see after the training session if Busquets is fit to play.

"Javier Mascherano will not be able to play tomorrow. He needs six weeks to recover and only four have gone by, so he will not be in the team."

Barcelona lost the first leg 4-0 at the Allianz Arena in Munich last week.
