Premier League: Ranking the 5 best attacking units in the league 

#3 Arsenal

The Gunners scored 73 goals in the league last season, and nearly half of those were scored by two gentlemen who seem to have struck up a relationship in attack - Pierre-Emerick Aubameyang and Alexandre Lacazette.

Aubameyang finished as joint top-scorer of the league last season with 22 goals and Lacazette finished with 13 goals and 8 assists (the highest for Arsenal in the league).

It's a relationship that Arsenal boss Unai Emery will hope to exploit this season in attack. His task will be to ensure there's a steady supply of chances for these men to do what they do best. Arsenal are sorely missing a link between midfield and attack, a role that Mesut Ozil usually is happy to fill, but he can't seem to find his best under Emery so far.

Arsenal will also need to find a third player to bear the responsibility for goals next season if they're serious about challenging for top spots. Henrikh Mkhitaryan bagged 6 goals in the league last time around but he'll have to find some extra goals or Emery will have to look elsewhere within the squad with the likes of Iwobi or one of the youngsters to provide.

That's where their new signing, Gabriel Martinelli might step in. His finishing isn't top-drawer yet, but he's got blistering pace that can be deadly to Arsenal's opponents, especially on the break.

Crystal Palace winger Wilfried Zaha may be another avenue for Arsenal if they do manage to land him. He netted 10 goals last season, and his zip and creativity in attack may be able to unlock a few more goals for this side as well.
