Three goals in seven first-half minutes fired an impressive Arsenal side into the semi-finals for the second time in three seasons.
Emile Smith Rowe had a goal ruled out for offside before setting up Nicolas Pépé for the opener. Alexandre Lacazette then tucked away a penalty after Bukayo Saka had been fouled, with Saka firing in the third.
Lacazette put the gloss on a professional performance with a well-taken fourth as the Gunners cruised into the last four, where they will face former boss Unai Emery’s Villarreal.
Arsenal proved they can be the big guns of this competition after putting on an emphatic display. They started the game with a real intent to get an early goal, and though a first was ruled offside, that simply added fuel to the fire. The Gunners had shown they meant business after conceding a late leveller in the first leg, and they never looked back after getting the opener. Dominant throughout, Mikel Arteta’s side were clinical with their finishing.
Arsenal have only failed to score in one of their last 28 UEFA Europa League matches.
Arsenal are unbeaten in 12 away games in European competition (W9 D3) – the longest run without a defeat on the road in their history.
Arsenal now face Villarreal in the semi-finals, with the first leg on 29 April and the return a week later.
Who will win the Europa League? That is the question on a every fans lips.
