Bayern Munich winger Arjen Robben is targeting a return for the DFB Pokal final against Borussia Dortmund on May 21, his osteopath has said.

Robben, 32, is currently training individually after suffering an adductor injury last month and has not played since Bayern's 0-0 draw with Dortmund in the Bundesliga on March 5.

The Netherlands international appears to have little prospect of being fit in time for the second leg of the Champions League semifinal against Atletico Madrid on May 3 but hopes to step up his recovery in the near future.

Hub Westhovens, who has been Robben's personal osteopath for several years, told Sport Bild: "Arjen currently can do a lot of running and sprinting exercise.

"I think that the return leg against Atletico is too early -- we don't want to rush anything. If everything goes according to plan, Arjen can resume team training by the end of this week or early next week."

Bayern have only three games remaining in the Bundesliga, with the final game coming on May 14.

Robben, who began training with the ball again on Friday, is more likely to make his return the following weekend, when Bayern take on Dortmund in the DFB Pokal final at Berlin's Olympiastadion.

"The cup final in Berlin is a realistic goal," said Westhovens, who is currently in Munich to assist his client during the rehabilitation.

The former Chelsea and Real Madrid star could also take part in the Champions League final on May 28 if Bayern overcome Atletico in the semifinals.

Robben had initially been expected to make a swift return from the injury but said last week that he "couldn't exactly say" when he would return but hoped to be back before the end of the campaign and added: "All in all, things are looking up."
