Ahead of tonight's Champions League clash, Bayern Munich coach Louis van Gaal has paid tribute to Manchester United goalkeeper Edwin van der Sar.

The pair go head-to-head in the Allianz Arena tonight 15 years after Van der Sar was part of Van Gaal's Ajax side that claimed Champions League glory at Juventus' expense.

Van Gaal said: "I always say Van der Sar is a manufactured goalkeeper. He is not so happy when I say it, but there are more natural goalkeepers in the world. He always works with his brain. That is his secret. He is a great role model for goalkeepers around the world."
