Manchester United are unhappy seeing Timothy Fosu-Mensah frozen out at Crystal Palace.
The Sun says United are growing agitated and may even consider recalling Fosu-Mensah, 19, and finding him a new club.
The Dutch star has made 11 appearances for the Eagles so far this season, but his last came on November 5.
He has made 12 appearances for United since joining from Ajax in 2014 and has two caps for the Holland team.
Palace were held to a 0-0 draw against Alan Pardew's West Brom side.
They have now become the first side in Premier League history to fail to score in ten away games.
