The Netherlands international has been sidelined due to injury for a number of weeks now, but a Bayern Munich comeback still seems to be far away at this point
The winger sustained a muscular problem while away on international duty with Netherlands back in November and has since been out of action.
Bayern were initially hopeful that Robben would be match fit in time for last weekend's Bundesliga clash against Borussia Dortmund, but the Dutchman eventually did not make the squad, and he has now revealed that his comeback has been delayed due to a recovery setback.
"The muscle injury has healed, but my back is causing me problems again. I had pain in my back once more last week," Robben told Bild.
"I don't know whether I can make my comeback this year. We will keep on working on my recovery and try and shake off the back problem with the help of the doctors.
"I will bounce back, though. I am looking forward to 2013. I am highly motivated to help the team and play a key role. The past three years have shown that I hardly miss any games after the winter break."
Robben has made only 10 appearances in all competitions for die Roten this term.
