Bayern Munich are set to retrieve the services of influential winger Arjen Robben when they face Manchester United in the Champions League quarter-finals on Wednesday. Robben, who missed the first leg with a calf injury, trained with the team on Monday and is likely to be part of the game. "I have hopes he'll be able to play, but we'll have to wait and see. His muscles are still strained," coach Louis van Gaal said. Bayern, who are currently on top of the Bundesliga table, will also regain the services of center-half Daniel van Buyten at Old Trafford.
