Ralf Rangnick has revealed how he helped Liverpool boss Jurgen Klopp get his first managerial job at Mainz.

The new Manchester United boss was confirmed earlier this week, after receiving his work permit, taking the job on an interim basis until the end of the season.

Though now working for Liverpool ’s bitter rivals, Rangnick’s friendship with Klopp goes back more than two decades.

In 2001, Klopp called Rangnick for advice after being offered the manager’s job at Mainz and the current United boss acted as his unofficial agent in the negotiations.

“I remember before Jurgen became head coach at Mainz and he called me,” said Rangnick .

“I was at Ulm at the time and Jurgen asked me what kind of money he should be asking for from Mainz.

“He didn’t have an agent, so I told him. In a way, I was his agent and I advised him what he should ask for.

“Jurgen said ‘ah, do you not think that is too much to ask?’ I told him it was the right thing to do - and I am pretty sure he got what he wanted.”

Rangnick’s influence at the top of the Premier League also extends to Chelsea boss Thomas Tuchel, having offered him his first coaching role at Stuttgart after retiring through injury.

Despite the new United boss maintaining his friendship with Klopp over the years, the former RB Leipzig manager didn’t need Klopp’s advice when negotiating his contract at Old Trafford.

However, Rangnick was keen to point out that he was not the main influence on the 54-year-old’s burgeoning coaching career.

“I didn’t ring Jurgen about coming here, but we have known each other since 1997,” he said.

“I was not his mentor - that was a coach called Wolfgang Frank - but we have always been in contact and had a good relationship with each other.

“We respect each other and that will continue.”
