Arsenal hero Martin Keown has questioned Louis van Gaal's tactics for Manchester United's defeat to Swansea City.
Keown felt Van Gaal asked too much of his young team.
He told the Daily Mail: "The formation that Louis van Gaal started with against Swansea - three central defenders and two wing backs - is a hard enough system for seasoned professionals to get right, let alone a group of youngsters, including a few making their debuts at Old Trafford.
"I've always felt it demands too much of the wing backs, who have to cover so much ground. If their positioning is not spot on, then the central defenders have to react and cover the danger, but this can result in your team shape being dragged from side to side. And that's exactly what happened to United on Saturday."
