Andrei Kanchelskis is the latest in a long list of former Manchester United players to slam the tactics of manager Louis van Gaal.
The Red Devils have played over five hours of football since their last goal - an Anthony Martial header in the 1-1 draw with CSKA Moscow.
United welcome CSKA to Old Trafford on Tuesday night and will be looking to end their barren run of three games without a goal.

And Kanchelskis, who made over 120 appearances for the Red Devils between 1991 and 1995, joins the likes of Paul Scholes, Owen Hargreaves, Gary Neville and Rio Ferdinand in blasting his former club.
As per the Manchester Evening News, the former Russian international told Sport Express: "The first game against CSKA showed that it’s possible to win against this team.
"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.
"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's attacking play has been well below-par in recent weeks. While Wayne Rooney has struggled to lead the line, the midfield has also failed to offer him much support.
But the answer to their problems may be to reintroduce Martial upfront at the expense of their captain. The young Frenchman has the frightening pace that Rooney no longer possesses and offers a completely different threat to the England international.
Some fans have been quick to suggest that Rooney's time at Old Trafford is coming to an end, but that is most definitely not the case. The 30-year-old still has the ability to influence United's attack and a move deeper could reinvigorate his career.
