Former Manchester United winger Andrei Kanchelskis has slammed Louis van Gaal by claiming that his tactics are "disgusting".
The Red Devils, who are currently fourth in the Premier League table have not managed to score in any of their last three games in all competitions.
United's last goal was scored in a 1-1 draw against CSKA Moscow last month, and Kanchelskis was not impressed with the display.
"The first game against CSKA showed that it's possible to win against this team," Kanchelskis told Sport Express. "I was at the stadium and I was surprised how disgustingly United played in the first half. A lot of ball control but no sharpness at all.
"In the second half it got better because of the substitution of Bastian Schweinsteiger, who was slowing the game down. I guess, Manchester United is not his team. It's in the history and tradition of Man United to play wide and be sharp at the flanks but there is nothing like this now.
"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. Van Gaal, of course, is a good coach but, in my opinion, he is not for Manchester United."
United will take on Group B opponents CSKA at Old Trafford this evening.
