Liverpool legend Graeme Souness has warned Manchester United not to expect any quick fix next season.
Souness thinks it will take United four transfer windows to turn the club's fortunes round.
He said on Sky Sports: "It's not a given that United will be back in the top four, whoever is the manager.
"It's not a quick fix.
"I think it's a minimum of four transfer windows - if it goes well - before Manchester United get back to where they want to be and should be. I'm talking about winning big trophies"
