The chances of Arjen Robben playing again this season for Bayern Munich appear slim as there is still no timetable for his return from injury.

The Dutch wideman has been out since last month's goalless draw with Bundesliga rivals Borussia Dortmund, and Bayern have revealed few details about his problem.

"I'm working on my comeback, but there is no time frame," the 32-year-old told Kicker.

"It's really frustrating because I was back in top condition again and was ready for the important games of the season."

A recurring groin injury has restricted Robben to just 15 appearances in the Bundesliga this season.
