Unai Emery ended his first campaign in English football on a disappointing note after missing out on the top four as well as losing the Europa League final to London rivals Chelsea.
However, with a new season comes new opportunities and the signing of David Luiz from the Blues could prove to be a massive boon if he is used rightly.
The Brazilian is one of the most experienced defenders in the league but he brings a lot more to the table than just defending.
Luiz is exceptional on the ball and has a wide range of passing skills in his locker. His positioning as a centre-half has been questioned at times, but Emery could use him in a different role which would benefit both the Brazilian and his new team this season.
Pep Guardiola's Manchester City took on Arsenal last season at the Etihad where Fernandinho was used in central defence. The Brazilian was given a unique role where he would stay as a centre-half in a back four when City did not have possession. But, when the Champions were on the ball, he would return to his natural number six position while the rest of the back line turned into a three-man defence.
Emery could deploy Luiz in a similar way this season where he could burst forward with possession and use his ability on the ball to pick out a pass or have a pop at goal from distance like he has on multiple occasions in his career so far.
When the Gunners lose the ball, Luiz could immediately slot back into central defence making Arsenal's back line compact when under attack. This would add much-needed steel while also massively boosting their attack thanks to Luiz's range of passing that could set the likes of Aubameyang, Lacazette and Nicolas Pepe through on goal.
Emery should look to emulate his compatriot Guardiola's system through Luiz's versatile positioning and, if the Brazilian could find the right balance between attack and defence, Arsenal may have a hugely successful campaign.
