Schalke coach Markus Weinzierl has no doubts about the quality of Eric Maxim Choupo-Moting.

The Cameroon international is being tracked by Stoke City ahead of the January market.

Choupo-Moting's current deal expires in June and the winger, 27, is tightlipped over his plans.

Weinzierl, meanwhile, says: "There are few qualities about which he does not have. Technically top, fast, strong.

"If he can bring his consistency to the team, all the better. Choupo is a top player."
