Bayern Munich have received a boost after Arjen Robben returned to training on Thursday following groin surgery.
The Dutchman was sent under the knife last month after managing to play the full 90 minutes just once in the league this season.
Bayern boss Jupp Heynckes later revealed he was not sure when Robben would be back, but he has now resumed work with his team-mates.
He trained for 45 minutes with the rest of the squad before undergoing individual fitness work, the club said.
"We will have to see from day to day how the groin reacts to this," commented Bayern assistant coach Peter Hermann.
Bayern have been playing well even without Robben and lead the Bundesliga standings with a five-point gap while also topping their UEFA Champions League group.
Robben, who helped Bayern to the league and German Cup double as well as the 2010 Champions League final in his first season, has been plagued by injuries since the Netherlands lost in the 2010 World Cup final to Spain.
"Robben is an important player in our team. It will be good when he is back," captain Philipp Lahm told reporters.
