Manchester United boss Ole Gunnar Solskjaer has suggested that some of his charges have been told to shape or ship out.
United have had a turbulent season but remain in FA Cup as well as Europa League and just three points off fourth-placed Chelsea in Premier League.
The Red Devils are unbeaten in eight - their longest undefeated run since Solskjaer's first 11 matches as caretaker manager - but the Norwegian suggested some unnamed players may have had enough opportunities.
"It is hard to say in percentages, but we are getting there, day by day," Solskjaer said of United's progress. "There are still some days here when I am not 100 per cent happy with what has happened, but you understand because we are human beings. They are disappointed, but get on with it.
"I am not going to feel sorry for you (the player), you have to make yourself available for the next game and competitive in situations. That is what I like. I like to see players who say, 'okay, he has left me out for two or three games without explanation'.
"I don’t have to explain every time. Sometimes I do, yeah, but it is a way for me to say I need more. You can’t just speak to them 100 times and say, 'now we need a change in you'. You have had opportunities.
"I've got to make decisions and one day… well, you give them one warning and that’s it probably, and then the next thing maybe they are not here anymore. You don’t have to explain every time then. You might have to think about it after.
"Football has changed and some players get affected by ‘I've made money, I've made this, I've won a trophy, I can sit back and relax’. I had the best of the lot as a manager. If you win something you move on."
Some of the players that have struggled in recent months include Jesse Lingard, Diogo Dalot, Andreas Pereira and Phil Jones. Jones has been left out of the squad in the four matches.
