Arsenal open their Premier League campaign with a crucial 1-0 win at Manchester United, exposing the key differences between the two sides.

Manchester United vs Arsenal proved an unusually high-tax affair for Week 1 of a Premier League season, and it was ultimately an error that divided the sides at Old Trafford.

Arsenal beat Manchester United 1-0 in their opening Premier League fixture on Sunday and boss Mikel Arteta believes his team showed resilience to 'find a way to win'. "We came here away and won which is a big result. We were clearly not at our best," Arteta told BBC Match of the Day.

Roy Keane has predicted where Manchester United will finish in the Premier League this season after picking out a key “worry” after defeat to Arsenal.

But Arsenal were given a helping hand by Altay Bayindir and, indirectly, Amorim. The Turkey international’s lame punch allowed Riccardo Calafiori to head in from a yard; if Viktor Gyokeres, the debutant striker, was supposed to be the final piece in Arteta’s jigsaw, there was something typical of his teams in that the goal came from the left-back.
