Erik ten Hag has blamed some of his Manchester United players for surrendering a two-goal lead at Tottenham to draw 2-2 on Thursday night.
The Dutchman said that they couldn't give 100 per cent in the battle for the Premier League top four.
United were in cruise control by halftime following goals from Jadon Sancho and Marcus Rashford, but goals from Pedro Porro and Son Heung-min in the second half salvaged a draw for Spurs.
"Some thought 90 per cent is enough, but we lose focus," Ten Hag said.
"That's why we give goals away. We did not do our job in positioning.
"I know they are not robots and it is a tough schedule, but when you are playing for Man United and playing away, you have to give (everything) on every occasion."
United next face in-form Aston Villa at Old Trafford on Saturday and victory would edge Ten Hag's side closer to finishing in the Champions League places.
Villa are in sixth and are level on points with Spurs, who travel on Sunday to play Liverpool, who are one place and one point further back.
