Ruben Amorim has three players who are perfect for his new look Manchester United system

The guesswork is nearly over. As Ruben Amorim continues to finetune his Manchester United plans for his debut as head coach at Ipswich this Sunday, we are getting closer to a first glimpse at his system and the players who will get the first chance to show they can adapt to it.

He has the passing range to distribute the ball smartly from that position and is comfortably defending the flanks, with the wing-back on that flank likely to be pushed
