Amad has shown his qualities in an inverted no.10-type role previously, particularly during his successful loan spell at Sunderland in the Championship, but has brought real energy and desire to the wing-back role in the new formation.
Such versatility is viewed as a real asset by Amorim, who has stressed that positions within his system change, in and out of possession.
"He was really good defensively, and really good attacking, so he has to continue to play like that," the head coach said after the 4-0 win over Everton. "You could feel at the end of the game, he was really tired, so we also have to manage that, to increase his physical ability."
Amad will hope to have recovered sufficiently from his exertions in order to face Arsenal in Wednesday night's game at the Emirates Stadium.
