Ralf Rangnick had advised incoming Manchester United manager Erik ten Hag to throw himself into negotiations with prospective signings.
United's failure to qualify for the Champions League is expected to impact their pulling power in the summer transfer market as it did in 2019, when they were reduced to recruiting Daniel James, Aaron Wan-Bissaka and Harry Maguire from Swansea City, Crystal Palace and Leicester City for £150million. None of them have been an outright success.
Interim manager Rangnick stressed Liverpool coach Jurgen Klopp, Thomas Tuchel at Chelsea and Manchester City manager Pep Guardiola are heavily involved in persuading targets to join their clubs. United gazumped City to sign Maguire and Cristiano Ronaldo in the last three years, while Jose Mourinho convinced Romelu Lukaku to join United over Chelsea in 2017.

Mindful of their stock, United are believed to be targeting certain players who are not generating intense interest from the Premier League's top three but Rangnick believes Ten Hag should be involved in selling United to targets.
When asked if esteemed players would still want to join United, Rangnick replied: "As a club, with regards to supporters, stadium, quality of training ground, I would say yes.
"But we also have to be realistic, as soon as other clubs like Chelsea, Liverpool, Manchester City are involved, then you need some good reasons, and somebody needs to explain to the players and that is why it is important what Erik thinks.
"I only know from my time with Leipzig and Salzburg, and I also know it from Jurgen and from Thomas, if they want players they're also involved. They speak to the players and the same is probably true with Pep, they will invite the players themselves.
"It's also about speaking to those players and finding out about their mentality and character, are they really players who are the best possible fit for this club.
"We just need to look into the other top clubs, the other top clubs in England, and also in some other countries in Europe and what kind of players do and did they sign in the past and then you get the answer yourself.
"This season showed that there are some problems that need to be solved and that need to be attacked and need to be settled. I am positive.
"Again, I have to say with Erik ten Hag Manchester United will have one of the best coaches that are available, probably one of the best coaches we have in Europe.
"And then it is about together with him, recruitment, together with the way the team is being trained and coached, are the two most vital things. And if those two things come together, I am very positive the fans here at Old Trafford and yourself can see a better kind of team and a better kind of football."
