#3 Alexandre Lacazette
The French striker showed why he is worth his massive price-tag this time. Lacazette might have struggled to score goals in recent matches, but he became Valencia's worst nightmare and gave Arsenal the important goal advantage at the Emirates.
In the game, he was ever present in the final-third and contributed significantly to the Gunners' shots on-target. Emery had been reluctant to pair him with Aubameyang on several occasions, but the manager's decision to start the duo together in this game eventually brought a positive result for Arsenal.
The 27-year-old equalised for the Gunners by clinically finishing Aubameyang's lovely delivery in the 18th minute. However, he did not stop there and netted his second goal from a thumping header to give Arsenal the lead. The Frenchman also had at least two more golden opportunities to score, but he was denied by Neto's brilliant saves.
