Belgium manager Marc Wilmots believes Kevin de Bruyne's career will stall if remains on the bench at Chelsea and should move if the situation doesn't change.
De Bruyne signed for Chelsea in January 2012 for a reported fee of £6.7m.
After a successful loan spell at Werder Bremen last season, the 22-year-old was expected to walk in to the Chelsea team this season but has since fallen out of favour with Jose Mourinho.
Mourinho has been openly critical of De Bruyne, questioning his attitude and professionalism and has limited his first team opportunities as a result.
De Bruyne has started just two Premier League games this season and appeared off the bench once.
His national coach hinted that his lack of first team football at Chelsea will start to hamper his international career unless the situation changes soon.
Schalke 04 have been linked with a move for the midfielder and Wilmots would be happy to see De Bruyne leave for the Bundesliga side.
Wimots also revealed that a number of clubs are interested in the Belgian international.
"My request is that Kevin de Bruyne plays regular first-team football," Wilmots told Sport-BILD.
"Everyone knows what he is capable of.
"Schalke is a special club for me and it would be great to see a player of this quality play for Schalke 04.
"Kevin de Bruyne is a player that many clubs are about to consider."
