Ralf Rangnick reportedly recommended four highly-rated players to the Manchester United hierarchy before stepping away from his interim role at the club - including Joško Gvardiol, who was outlined as a 'must-buy' target.
Rangnick was hired by United to steady the ship on a temporary basis after Ole Gunnar Solskjaer was axed, with the German agreeing to take up a consultancy role to work with whoever the club appointed as their new permanent manager at the end of last season.
However, Rangnick endured a torrid time at Old Trafford and opted to take on a new role with the Austria national team just before he was due to embark on the consultancy role that he had previously agreed.
