#1 Unai Emery
You just cannot expect a better start than this for a new manager. In just a few months time, Unai Emery has given this team hopes of qualifying for Champions League football, the same squad who finished 6th on the league table last season. Though he has experienced some bumps down the lane, he never refrains himself from trying new tactics and systems, which is how a modern football manager should be.
Efficiency alongside beautiful football is what every club aims for, and Unai Emery has been able to bring it to the Emirates in no time. The term 'Emery-ball' is getting quite famous with time, and this will be something the Gooners will always remember.
Considering how they started the season, it would've sounded ridiculous to say Arsenal would fight for the third position against sides like Manchester United, Chelsea and Tottenham, but the fact that the Gunnars are actually competing for the third spot and are currently above United and Chelsea is really impressive.
The Spaniard's man-management and tactics have brought a different dimension to the Arsenal squad and have always impacted the Gunners' game. Arsenal looks a resolute and a well-organized side who are more keen to come out on top in every single battle against the top dogs in the Premier League.
Unai Emery has bagged 12 points against the top dogs in the Premier League this season - double the number of points Arsene managed to earn last season. Arsenal under Unai Emery looks determined to win, and every player has yielded huge improvements in their game under the Spanish boss.
