Bayern Munich winger Arjen Robben has revealed that he is 'unsure' whether he will return against Valencia on Wednesday.
The 27-year-old is suffering from a groin injury he picked up on international duty with the Netherlands, but he is hopeful of returning for the Champions League clash at the Allianz Arena.
"It's looking good. It's something in my back, which made my groin feel bad. We have to be reasonable and smart now because we have so many important matches in the next few weeks. I'll have to wait and see. We're taking each day as it comes," he told FCB.tv.
Robben scored 19 goals for Bayern last season.
