Rangnick - Ralf Rangnick warns Man Utd need up to 10 new players in rebuild after Liverpool thrashing at Anfield

He resigned from Red Bull in 2020, with a reported move to failing during negotiations.

Hence, here's a look at who is Ralf Rangnick, the person who is nicknamed as 'The Professor of Football' by some.

Ron hurt his knee after his penalty winner in Thursday's 2-1 defeat of Arsenal.

I am excited to work with the players we have here.

Rangnick finished with a record of 36 wins, 16 draws and 34 losses.

The German media nicknamed him the 'German Professor', probably unfairly and with derision.
