Former United striker Robin van Persie has urged the club to stick with Manager Ole Gunnar Solskjaer in order to bring needed stability to the club.
The Dutchman told Sky Sports:
“Especially after Alex Ferguson left, everyone realised that it would be tough to stick to that level that Ferguson achieved for all of those years.
“I think everyone could see that. Now [David] Moyes has been there, [Louis] van Gaal, [Jose] Mourinho and Solskjaer.
“Ferguson took time to adjust and get to a certain level. I don’t think that it’s ideal for the club to keep changing the manager every one or two years.
“If you go for Solskjaer, go for him and give him time, that is what I think because the club needs to find some stability.”
Van Persie also admitted that it would be difficult to compete against league leaders Liverpool, and rivals Manchester City.
He added: “Now they win against Chelsea [On Monday night] and to be fair they had a good game ‘But you never know what’s going to happen in the next few games. It’s not consistent enough to be able to really play for the trophies.
“It is difficult because you have to compete against Liverpool, who are unbelievable and Manchester City, who are brilliant.
“Manchester City are not on the same level this year, but based on the last couple of years, they and Liverpool have been unbelievable.
“That is the level United have to go to, that is consistency, and that is the hardest thing in football because the league is tough.
“Even if you play against teams like Burnley away, teams like that are really difficult to get points against. You have to get everything right and that is a big challenge to get that consistency.”
Since the departure of Sir Alex Ferguson in 2013, United have had four different coaches at the helm.
