Liverpool Coach Jurgen Kloop says with fellow German Ralf Rangnick set to join Manchester United, teams will be in trouble.
Rangnick agreed to take charge at Old Trafford for six months after the dismissal of Ole Gunnar Solskjaer on Sunday.
The German is considered a role model to current top young German managers Thomas Tuchel, Julian Nagelsmann and Klopp himself.
“Unfortunately a good coach is coming to England, that’s how it is, to Manchester United,” he said.
“Ralf is obviously a really experienced manager.
He built most famously two clubs from nowhere to proper threats and forces in Germany with Hoffenheim and Leipzig.
United will be organised on the pitch, we should realise that — that’s obviously not good news for other teams.
“But all coaches in the world, we need time to train with our teams and Ralf will pretty quickly realise he has no time to train as they play all the time, so that makes it a bit tricky for him.
Apart from that, a really good man and an outstanding coach, if it happens, will come to England,” Klopp noted.
The 63-year-old is not expected to be at the dugout when United clash with league leaders Chelsea on Sunday.
