Philipp Lahm, Germany's World Cup-winning captain and Bayern Munich's current skipper, hinted that he may retire from football at the end of the season.

Lahm stepped down from international football after leading Germany to the 2014 World Cup and has a Bayern contract until 2018, but admitted he might hang up his boots in June 2017.

"I wouldn't rule it out," Lahm, who turns 33 on Friday, told magazine Sport Bild.
