#1 Efficiency in the Final Third (finishing)
Finally, Aubameyang and Lacazette have started together. The Gooners had been waiting for this since the start of the season and Unai finally went with fans. It didn't backfire though, but Arsenal could have scored plenty more, as they got chances in abundance to make the scoreline more one-sided.
The Auba-Laca duo got themselves goals against Cardiff City yesterday, with Lacazette bagging an assist as well, which led to a classic finish by Aubameyang.
However, Aubameyang opened his account just last weekend, going goalless in the three fixtures since the start of the season, despite starting in all three.
After joining Arsenal in the winter transfer window last season, he bagged 10 goals and 4 assists in just 13 games, just two fewer goals than Hazard (equalling the assist tally) who played the whole season.
Aubameyang is a striker of great calibre, but his starting games this season says otherwise. It may be a problem of integration, but if he continues to not score, I am afraid Arsenal might see themselves finish outside of the top four.
