Andrei Kanchelskis believes Louis van Gaal is the wrong manager for Manchester United due to his pragmatic style.
Van Gaal has been criticised this term following some increasingly turgid displays from his side.
Man United have failed to score in over five hours of football and the pressure is on them as they prepare to face CSKA Moscow on Tuesday night.
Kanchelskis, who played for United under Sir Alex Ferguson in the 1990s, slammed van Gaal for turning his players into “robots”.
“Van Gaal is too pragmatic, his footballers play like robots. They are kept within a strict framework, they are not allowed to improvise contrary to what Ferguson allowed us to do,” Kanchelskis said.
“Van Gaal, of course, is a good coach, but in my opinion he is not for Manchester United. Their history and tradition is to play wide and be sharp at the flanks – but there is nothing like this now.
“I’m looking at his game for the second season now. He says that the transformation is going on, but I still couldn’t understand what he is looking for. There is an impression that he doesn’t know what he wants. No creative players, no wingers. Nobody could serve Wayne Rooney.
“The current Manchester is not the same as it was under Ferguson.”
Van Gaal has been coming under intense scrutiny as of late and a negative result against CSKA would do little to help his cause. United have built a rich history on attacking football and the Dutchman is failing to continue that tradition. He needs to turn it around and quickly.
