Ruben Amorim has already had the green light from Roy Keane to make Man United tactical tweak

Almost five years after Bruno Fernandes swapped Sporting Lisbon for Manchester United, Ruben Amorim looks set to follow in his fellow countryman's footsteps.

Amorim is on the brink of becoming United's new manager after the club agreed a deal with Sporting Lisbon to secure the services of the 39-year-old.
