Manchester United's once intimidating reputation has been dwindling in recent years, with the Red Devils often seen as an opportunity for three points against a Premier League giant.

Ruud van Nistelrooy has taken over on an interim basis while United strive to secure their new manager. Amorim has spent his entire coaching career in Portugal, managing Casa Pia, Braga and Sporting.
