Former Manchester United striker Dimitar Berbatov believes the club should hire Ole Gunnar Solskjaer immediately.
The Norwegian is expected to win the manager's role permanently after turning the club's fortunes around since replacing Jose Mourinho in an interim role late last year.
Berbatov told Betfair: "Talking as a former player I am sure the current playing staff at the club would welcome some clarity on Solskjaer's status at the club.
"It is tiring to have so much change in the managerial position. A club needs that stability at the top.
"For a team that did not change manager for 25 years to have so much churn in such an important role suggests they don't know what they're doing.
"With all the work he has done I don't think it would be fair to him or the players if they don't announce that he is going to stay in charge.
"Ole was able to raise the spirit, the team, everything at the club. He was the guy who took responsibility in a difficult situation.
"Purely on what he achieved so far he deserves an extension. He has earned it.
"He is young for a manager, an ex-United player - it's the best combination for the club to build for the future."
