Raphael Varane was replaced with an injury in Manchester United’s Champions League match in Atalanta on Tuesday night.
The French international returned just from a groin injury in United’s 3-0 win over Tottenham at the weekend, playing 90 minutes as the Red Devils rioted.
But with Man Utd 1-0 down at Atalanta, the defender dropped to the floor from the ball in discomfort and was replaced by Mason Greenwood after 38 minutes.
Ole Gunnar Solskjaer has been guilty of rushing back injured or incompetent players several times as United boss. Club captain Harry Maguire only had a day’s training on grass under his belt when he returned from injury earlier this season and looked miserably out of shape in a 4-2 loss to Leicester.
Victor Lindelof got a slap in the weekend’s win against Spurs, but was not risked against Atalanta, with Eric Bailly replacing him in the starting lineup.
United have struggled defensively this season, with their zero at Tottenham their first in ten games in all competitions. They conceded 11 goals in three games while Varane was injured last month, and Solskjaer will hope that one of his key men will not face an extended period on the sidelines.
