Munich - Waylaid FC Bayern München midfielder could play again before the end of the year, according to club sporting director Matthias Sammer.

The 30-year-old hasn't kicked a ball for the 23-time Bundesliga champions since aggravating a knee injury in the Major League Soccer (MLS) All-Star game on 6 August, but Sammer is optimistic the World Cup-winning hero's luck could be about to change.

'On the mend'

"There's no reason to rule out a return this year," the former Borussia Dortmund defender told Germany’s largest specialist football magazine, Kicker. "In fact, it's not beyond the realm of possibility that he'll play again in 2014. His knee's on the mend and we're optimistic about it. He's made great progress."

Schweinsteiger, who was named Germany captain following Bayern team-mate Philipp Lahm's international retirement, has missed 59 of Bayern's 176 games since 2011, as well as 21 from 47 for the national team, because of injury.
