#2 Alexis with a point to prove, impresses

For a player who had only scored four goals in 32 appearances for Manchester United before this game, it felt inevitable that Alexis Sánchez would score against his former club at the Emirates. Doing exactly that, it proved only the start in an impressive performance from a player with something new to prove under Solskjaer's watch in Manchester this season.
Every touch and opportunity that Arsenal fans had, they let Sánchez know exactly what they thought of him. Their former talisman, who unceremoniously departed for the Red Devils twelve months ago, had struggled considerably with troublesome injuries and poor form under Jose Mourinho.
Oh, how Arsenal fans wish they still had him now. Despite initially having troubles dealing with Ainsley Maitland-Niles down the right, his intelligent movement, attacking positioning and awareness proved key as he continued to stretch the Arsenal backline.
The finish beyond Cech was well-executed and a difficult one to pull off as the onrushing goalkeeper attempted to close down the angles. It proved futile, against a world-class player who certainly hasn't lost his ability overnight.
He worked hard throughout - as he so characteristically does - before being substituted for Martial with 20 minutes to play. United will be hoping that this is the start of a rejuvenated Alexis as their momentum continues to rapidly build.
