It seemed to me that Arsenal was just willing to hold the ball, not looking to score for the early part of the half. But Napoli started to grow into it following the Callejon shot in the 17th minute. Milik was called offside in the 24th minute. But after seeing the replay, I'm not entirely sure that he was. However, Lacazette's free-kick is certainly a dagger. I don't think Meret could see it with the wall, and he assumes the Frenchmen is shooting towards his right, and the small step he takes in that direction kills any chance of saving that shot.
Arsenal's wingbacks were fantastic in nullifying our width the entire game. Our Crossing was woeful in the first half, and it killed the chances that were created. In the second half, they didn't create much, except when Monreal tried to clear one, but instead sent it straight to Cech.
Whoscored.com has Napoli's best player as Fabian Ruiz at 7.4, and this feels very deceiving as he struggled to create much on the left. I felt like Kolasinac controlled him for much of the match.
Overall, a disappointing end to the Europa League campaign, but credit to Unai Emery and Arsenal as they really controlled the match and weren't threatened.
