Gary Neville urged Ralf Rangnick to completely overhaul Manchester United both on and off the pitch after the German was confirmed as the club's interim manager on Monday morning.
Rangnick has been hired on a short-term contract to coach the first team until the end of the season before he then takes on a consultancy role for two years.
The German replaces Ole Gunnar Solskjaer, who was sacked earlier this month, while the Red Devils look for a new permanent manager.
