Newly crowned German champion Bayern Munich might have drawn 3-3 with Hoffenheim over the weekend, but Dutch winger Arjen Robben insists that the defending German treble winner won’t be so complacent against Manchester United in the UEFA Champions League quarterfinal first leg at Old Trafford on Tuesday. "It's going to be a tough duel and we've got to watch out," the Netherlands international said. "The media and public opinion is that Manchester are not in good shape and that we're going through to the semis, but I don't like that at all. You only need to get distracted for a second and you lose against Manchester United. If you lose concentration and lose the ball, then you get punished there."
