Ralf Rangnick joining Manchester United is bad news for the other Premier League teams, according to Liverpool manager Jurgen Klopp.
Rangnick is ready to take over as Manchester United's caretaker manager for the remainder of the season after reaching an agreement with the club earlier this week.
He is set to take over as manager next week, ahead of the Red Devils' match against Arsenal at Old Trafford on Thursday night.
The 63-year-old has enormous clout in Europe and is widely regarded as the "godfather" of current German managers, with Klopp regarded as one of his pupils.
Their friendship dates back over two decades, and Klopp has admitted that Manchester United acquiring him would be bad news for the rest of the Premier League.
Rangnick, he said, "formed two clubs out of nowhere and converted them into big forces in Germany," and he claimed that, despite his various responsibilities, he is still a coach at heart.
Klopp said in a press conference: “Unfortunately, a good coach is coming to England and to Manchester United.
“He is a really experienced manager, built two clubs from nowhere to a proper force in Germany in Hoffenheim and Leipzig.
“He did a lot of different jobs in football but it was always his first concern was always being a coach.
“United will be organized on the pitch, I think we have to realize that and obviously it is not good news for other teams.
“He is a really good man and an outstanding coach is coming to England.”
Rangnick is also likely to play a key influence in the appointment of Manchester United's new permanent manager.
