3. Arsenal has a more composed defence
Arsenal finally look as though they have a defence capable of maintaining a run for the title. Arsenal back line has not looked as strong as it does currently since the mighty Invincible side.
The world-class Laurent Koscielny has finally found a good central partner in Shkodran Mustafi and with the excellent Bellerin and Nacho Monreal at full-back, there are few better back lines in the division – especially with Petr Cech in goal behind them. In defence, Shkodran Mustafi has been rock-solid alongside Laurent Koscielny, with glaring only minute errors this season.
The German seems to have already established a good understanding with his partner at centre half. Hector Bellerin has only become better with more experience, and Nacho Monreal has been reliable as ever. With Holding, Gabriel, Gibbs and Mertesacker as defensive back up Arsenal look like the best the defence in the Premier League.
