Metzelder to quit at the end of the season

Schalke defender Christoph Metzelder has confirmed he will retire at the end of the season.

The 32-year-old former Germany international will hang up his boots after Saturday's trip to Freiburg.

"I am just being honest with myself and I feel that I am no longer physically able to play consistently at this level," he said.

"And after 13 years, the fire inside me, which is necessary for this job, has burnt out."
