Belgium coach Marc Wilmots has confirmed he has been contacted by Bundesliga club Schalke 04 over their coaching vacancy, Belgian press reported on Friday.

"I have been contacted by Schalke, but I really don't know myself what I will do," said Wilmots, who scored in Schalke's UEFA Cup final win over Inter Milan in 1997.

"I have a get-out clause in my contract with Belgium, but that does not mean that I will go," he said.

Wilmots played for Schalke between 1996 and 2000 and was briefly player-coach at the club in 2003. He also enjoyed spells at Standard Liege and Bordeaux.

The attacking midfielder played at an impressive four World Cups with Belgium, and then coached them at a fifth in Brazil in 2014.

Italy's Roberto di Matteo stepped down as coach of Schalke on Tuesday after a disappointing season that saw them finish sixth in the Bundesliga.
