Lewandowski, Robben doubtful for Barca

Berlin - Bayern Munich's top scorers Robert Lewandowski and Arjen Robben are doubtful for next Wednesday's Champions League semi-final, first-leg, against Barcelona after suffering injuries in the newly-crowned German champions German Cup defeat.

Bayern were knocked out of the Cup on Tuesday, ending their hopes of a second treble in three seasons, after losing the penalty shoot-out 2-0 to Borussia Dortmund as the semi-final finished 1-1 after extra-time.

Lewandowski, who has scored 22 goals this season, was taken to hospital after suffering a knock to the head following a goal-mouth collision with Dortmund's Australia goalkeeper Mitchell Langerak late in extra time.
