Sporting were mostly left to fend on the break. Fortunately for Amorim, Gyokores is a one man counter attack. When he was matched up with 19 year old debutant Jahmai Simpson-Pusey there was no stopping the dynamic Swede, a clipped finish over Ederson making amends for an altogether sloppier effort half an hour before.

Rúben Amorim will ultimately be judged at Manchester United on closing the gap on Pep Guardiola, and on this stunning evidence he is ready for the challenge.The Portuguese coach predicted fans comparing him to Sir Alex Ferguson with victory against the great Guardiola in his final match at Estádio José Alvalade before heading to Old Trafford.

Ruben Amorim has a chance to quickly endear himself to Manchester United fans when he comes face to face with Pep Guardiola.
