Philipp Lahm admits the loss to injury of Arjen Robben is a big blow for Bayern Munich going into their Champions League clash with Manchester United.
Bayern insiders rate his chances of facing United as "less than 50-50".
Lahm admitted the loss of Robben would tilt the tie United's way, saying: "When you consider the importance of those goals against Fiorentina and Schalke, there is no doubt it will be harder than ever for us, if Arjen is ruled out."
