Robben's Bayern Munich inclusion still not known
Robben sustained an injury during the weekend's loss to Stuttgart and is under a cloud of uncertainty going into the quarter-final first leg with Munich boss Louis van Gaal he will play no part unless he is 100% fit.
"We're doing everything we can to make sure Robben is fit," said van Gaal. "But I don't want to take even the smallest risk.
"He has to be absolutely fit and only then will I put him in the team. His muscles are tired and I have to be absolutely sure he is 100 per cent fit.
"It's a big game and we can't afford to have a player who is only 80 per cent fit."
