The North London side came from one goal down to grab the important win thanks to a brace from Alexandre Lacazette and one strike from Pierre-Emery Aubameyang.
A Europa League crown will hand Unai Emery’s men the slot for next terms Champions League.
And the win in the first leg of the semi-final encounter with Valencia just took them closer to that dream.
