Erik ten Hag has warned Harry Maguire and Victor Lindelof they must be ready to answer Manchester United's SOS – or find another club.
Maguire and Lindelof, frozen out for much of the season, will start at Nottingham Forest on Sunday, with first-choice central defence pairing Lisandro Martinez and Raphael Varane both injured.
Ten Hag said he will not accept excuses from players about not being ready to step into the starting line-up and said they should not be at United if that is the case. “Every game is a battle, every game is a fight and you have to be ready for that fight,” said Ten Hag.
