Ange Postecoglou has said Ruben Amorim will succeed at Manchester United if he is given two years to work at Old Trafford.
Since joining United from Sporting CP in November, only five teams have won fewer Premier League points and he has won just nine of his 20 matches in charge in regulation time.
United have lost seven of their last 11 league games and sit in 13th place ahead of Sunday’s trip to Tottenham Hotspur, who lie in 14th place with Postecoglou under mounting pressure over his position.
