Jose Mourinho wants his Manchester United players to think like Roger Federer and adapt to different playing surfaces for their Champions League opener on artificial turf in Switzerland.
Playing against Young Boys on Wednesday in Federer's home country, Mourinho does not want to make excuses for a field he does not like.
The United coach says the "big man (Federer) ... has also to win on the surfaces that he is not in love with, so we have to do it."
