Manchester United legend Paul Scholes has been very critical of the club's striker Anthony Martial, attacking the forward's positioning off the ball.
Speaking to BT Sport, the former midfielder said: "The movement from the center-forwards was virtually non-existent. Anthony Martial, the amount of times I looked up when a midfielder had the ball, he was just stood in between the two center-backs doing nothing.
"I'm a big fan of Martial but the amount of times I looked up and he was walking, he has have to realize as a center-forward - every now and again you have to move if you're going to score a goal. You can't just be walking in front of two center-backs doing nothing."
The French international scored United's goal in the 2-1 loss against Istanbul Basaksehir, but that was not enough to help the Red Devils mount a comeback.
Martial's only two goals this season have come during his last two appearances.
