Arsenal 3-1 Valencia: 5 things we learned

#1. Alexandre Lacazette grabs two but should have had four

Lacazette wheels away to celebrate one of his two goals - though he should have had more

Alexandre Lacazette was the Man of the Match and once again showcased why he - not Aubameyang - is their most complete attacking option during this 3-1 victory. With 18 goals across all competitions this season, the pair have now combined to score 43 goals in 18/19. Yet both could have so much more and it ultimately boils down to finishing promising chances when they're presented on a plate.

His hold-up play and ability to create opportunities for others, bringing teammates into attacks, remains an underrated facet of his game. It proved pivotal during the build-up to their first goal, where he combined alongside Ozil and Auba to equalise at a vital time to settle the hosts' nerves.

However, he should have netted a first-half hat-trick and then capped a great performance with more after the break. Aubameyang's floated cross into the box was perfectly-weighted for the Frenchman to convert from close-range, yet he failed to connect with his attempted header and the danger was averted.

Then three minutes later, he saw two efforts in quick succession thwarted by the combination of an alert Neto and Gabriel's last-ditch sliding block. Striking goalwards at Neto's near post, the Brazilian read his effort and snuffed it out dramatically with his outstretched leg.

You could be forgiven for reflecting back twelve months ago, to the first leg of their Europa League semi-final clash with Atletico Madrid. Diego Simeone's side were a man down for nearly 80 minutes and still managed to draw 1-1 while netting a crucial away goal. If not for Aubameyang's stoppage-time strike, they would've been travelling to the Mestalla with a much less comfortable advantage and renewed fear that history would repeat itself twelve months on.
