Interim manager Ralf Rangnick has claimed that it 'should not take too long' for Manchester United to start challenging for silverware again.
Despite Monday's 3-0 victory over Brentford in the Premier League, United are clear outsiders to qualify for next season's Champions League with fourth position in the standings looking unlikely.
Ajax boss Erik ten Hag has already been appointed as a replacement for Rangnick, who will take on an advisory role, and the pair will both play their part in an Old Trafford rebuild during the upcoming transfer window.
While Rangnick has revealed that the duo are yet to hold discussions regarding new players, the German acknowledged that "top-quality players" need to arrive at the club.
Speaking to Sky Sports, Rangnick said: "So far we haven't been able to speak. Erik's focus is on winning the Dutch league, our focus was on our games.
"It's obvious quite a few players will leave and there is a need for top-quality players. I strongly believe that if everyone works together we can bring Man United back to where we need to be.
"Other clubs only needed two or three transfer windows to challenge but from now on we need to bring in top-quality players who really help raise the level. If this happens then I don't think it should take too long."
United end the season with visits to Brighton & Hove Albion and Crystal Palace respectively.
