#1 Alexandre Lacazette
Aubameyang might be the out-and-out goalscorer for Arsenal right now, but he's nowhere near as well-rounded as his striker partner Alexandre Lacazette. The Frenchman has scored an impressive 13 times in the Premier League this season and has also notched up nine assists in the process, which indicates that he shares a strong chemistry with the players around him.
Another indication of how important he is to the team is the fact that he has played in 30 games out of the 33 for the Gunners in the league this season. Clearly, he's relied upon by Emery not just to score but to set up chances for his teammates too. He has a big role to play in the Arsenal side and he does it well.
Lacazette's pace has been the main source of his goals as opposing defenders can't catch up with him to save their lives. Often times, he leaves the defenders for dead which allows him to go one-on-one with the keeper and more often than not, wheel away in celebration shortly after.
