Sead Kolasinac and Shkodran Mustafi are part of a revolt against Schalke boss Christian Gross, according to reports in Germany.

ESPN’s Derek Rae reports that various German sources claim there’s currently a player revolt ongoing against head coach Christian Gross.

The players are reportedly unhappy with everything from the coach’s tactics, to his training methods, the tone he uses, and the fact he confuses player names.

Bild claim the rebel players at the forefront are Sead Kolasinac, Klaas-Jan Huntelaar, and Shkodran Mustafi. Schalke are formally denying that there’s any kind of revolt going on or that there are internal calls for Gross to be sacked.

Schalke are rock-bottom of the Bundesliga with a fairly sizeable gap to the nearest club, so you can understand any unrest there might be among the squad.

But it’s surprising to see loanee Kolasinac and new signing Mustafi reportedly leading a rebellion. The duo only joined from Arsenal in January. Obviously, they want their new club to stay up, but this is a risky way to go about trying to improve their situation.

For what it’s worth, both Mustafi and Kolasinac were in the starting lineup against Stuttgart on Saturday, so the reports haven’t affect Gross’ team selection.
