Ole Gunnar Solskjaer and his coaching staff are understood to be unhappy over Gary Neville’s role in the anti-Glazer backlash at Manchester United.
The Sky TV pundit was praised for passionately criticising attempts to launch a European Super League.
But there are concerns that his continued attacks on the Glazers helped to fuel Sunday’s violent protests, which led to the game against Liverpool being postponed.
It has been rearranged for May 13, meaning United face four games in eight days.
