Some Manchester United players “need a reality check” after a poor run of form, says boss Ole Gunnar Solskjaer.
United have lost five of their past seven games in all competitions and were knocked out of the Champions League by Barcelona on Tuesday.
They are sixth in the Premier League, two points behind fourth-placed Arsenal, with five matches remaining.
“Most of the players have really impressed me with their attitude,” said Solskjaer.
“But of course there are some that need to get a reality check on where they’re at.”
Asked if forward Anthony Martial, who has scored three goals in his past 15 appearances, was one of those players, Solskjaer said: “I’ve spoken to individuals – and Anthony is one I’ve spoken to – and they know what we expect.
“He has a massive talent, he signed a new deal and he knows we believe in him, so he needs to keep on working.
“Anyone that plays for Manchester United has to deliver to stay in the squad and Anthony is not different to the other forwards like Marcus Rashford, Romelu Lukaku and Alexis Sanchez we have to choose from.”
As well as two defeats by Barcelona, United have been beaten in the Premier League and FA Cup by Wolves and lost to Arsenal in the league last month.
