Manchester United have been accused of creating an "absurd" situation with interim boss Ralf Rangnick which is likely to result in a "wasted" season.
The Red Devils have had three men lead the team this season, which is symbolic of their lack of consistency.
Ole Gunnar Solskjaer was axed last year with Michael Carrick filling in until Rangnick arrived.
The German is now taking charge until the end of the season, at which point a permanent successor is poised to come in.
Former United star Teddy Sheringham has taken aim at the club's decision making throughout the season, which will not have gone down with the playing squad.
Sheringham told Genting Casino : "In the main, when we're talking about Man United, I think the real problem goes back to Rangnick coming in, another interim manager. It's just absurd for me.
Who should be the next Man Utd manager? Have your say in the comments!
"United had an interim manager in Michael Carrick, they let him go and appointed another, it just brings uncertainty to a group of footballers that should be playing at their highest level."
Rangnick has made certain changes with players, who were formerly regulars under Solskjaer, now fighting for their position.
Diogo Dalot has been a big winner, coming in for Aaron Wan-Bissaka at right-back, for example.
The German has attempted to get his methods across but performances have not greatly improved even if there has been an upturn in results.
Sheringham has pointed to the constant change in instructions as a major problem for the players.
Rangnick has taken a different approach to his predecessor and the man who replaces him, potentially Mauricio Pochettino, is poised to again bring his own ideas.
"Rangnick's obviously going to chop and change with who he likes and who he doesn't like," added Sheringham.
"A footballer's mentality, if you are left out for three or four games is, ''I really want to get back in the team,'' but when it's an interim manager you can wait till the end of the season and say, ''Do you know what? He'll be gone before I go, so I'll wait till the next manager comes in''.
"If he leaves at the end of the season, and then someone completely different, like [Mauricio] Pochettino, comes in, it's a whole new vibe of how you want to play football."
He then added: "This season's going to be lost. It will be wasted and you have to start again. If the next manager brings in his own staff, his own players – it's just a whole new revolution again."
United are currently battling to ensure they finish in the top four as they face up to a fifth consecutive season without any silverware, unless they can win the Champions League.
