Arjen Robben: Comes off injured against Monchengladbach

Arjen Robben is set to miss Bayern Munich's Champions League quarter-finals against FC Porto next month amidst reports he is out for six to eight weeks with torn stomach muscles.

The 31-year-old was taken to hospital after suffering the injury in the first-half of Bayern's shock 2-0 German league defeat to Borussia Moenchengladbach on Sunday.

It was Bayern's first home defeat of the season and only their third in all competitions after losing to Manchester City in the Champions League's group phase and at Wolfsburg in the Bundesliga.

The Dutch Football Federation (KNVB) has confirmed Robben will miss Saturday's Euro 2016 qualifier against Turkey and next Tuesday's friendly against Spain.

German daily newspaper Bild claim Robben will be out for up to eight weeks with Bayern facing Porto away on April 15 before the return leg at the Allianz Arena on April 21 for a place in the Champions League last four.

The fleet-footed Dutchman will definitely miss Bayern's next German league match at Borussia Dortmund on Saturday April 4 and their German Cup quarter-final at Bayer Leverkusen four days later.

He has scored 17 goals in 21 Bundesliga matches, making him Bayern's top scorer this season, and has netted twice so far in their Champions League campaign.

"World-class is hard to replace," said Bayern's director of sport Matthias Sammer.

"You have to deal with setbacks. That is the feature of a winner and we want to be winners."
