More knee problems for Bayern's Breno

Bayern Munich defender Breno saw his comeback effort take a step back as it was confirmed that the Brazilian will require another operation on his knee.

The 22-year-old sustained a torn ACL in March 2010 before injuring his meniscus toward the end of the last season.

Breno has yet to appear in a match for Bayern this campaign and was arrested in September 2011 under suspicion of arson.

And now his comeback effort has been derailed as tests have confirmed the need for another surgery.

The former Sao Paulo man appeared in 18 games in all competitions for Bayern last term, but his future is in doubt with his contract expiring at the end of the season.
