2. Hummels has tactical flair.
Arsene Wenger is more known for his philosophy than his tactics and a naturally tactical player would boost Arsenal’s tactical displays in the game.
As a player he is accustomed to both the deep block and the high pressing defensive lines unlike Per Mertesacker whose lack of pace troubles him when Arsenal press higher. As a top organiser in defence, Hummels can actually prove to be a great leader and drive the team mentality from the back. From the past years, we know Arsene Wenger as a manager, gives a lot of room for flair and would enjoy managing Hummels.
