David Alaba: 'We will beat Barcelona 4-0'

Bayern Munich defender David Alaba has insisted that his team will overcome Barcelona in the semi-finals of the Champions League.

Bayern must overturn a three-goal deficit in the second leg, but Alaba does not believe that will be a problem and has backed the German champions to win 4-0.

Alaba, who is on the sidelines with a knee problem, has also vowed to be fit for the final on June 6 if Bayern make it.

"We'll win 4-0 and I hope I'm fit enough to play in the final in Berlin," the 22-year-old told reporters.

Lionel Messi scored twice for Barcelona in the first leg, before Neymar added a third in the fourth minute of stoppage time.
