Bayern Munich forward Arjen Robben has given fans hope that he could be back scoring goals after taking part in training Thursday for the first time since undergoing groin surgery in October. The 27-year-old Dutch international\'s appearance has raised hopes he could be ready for Bayern\'s league match at home against reigning champions Borussia Dortmund. It also comes in timely fashion as the Bavarian giants get used to the absences of Bastian Schweinsteiger, who is out till January with a broken collarbone, and midfielder Anatoliy Tymoshchuk, who is serving a three-match ban. Robben went under the knife early October to repair an injury that has restricted him to just four league appearances for Bayern this season. The ex-Chelsea star was also forced to miss the Netherlands final UEFA EURO 2012 qualifiers at the start of October.
