There is perhaps no player in Europe better than Kante at aggressively and tirelessly breaking up play. Premier League supporters, similarly, all know how adept Matic can be at fulfilling a similar role. Yet, against Arsenal, neither seemed to know what they were doing in the system played. Antonio Conte has been playing a 4-1-4-1 formation since the start of the season, with Kante handed the job of protecting the back four and Matic given licence to roam forward. But this system was torn apart by Arsene Wenger’s side. Kante spent the 90 minutes one step behind Arsenal, chasing the ball to little avail and failing to provide support for his defence. As for Matic, his role is difficult to understand, leaving many wondering what exactly his job is. Has he now become a playmaker? Does Conte expect the Serb to work with Kante? If so, he’s not fulfilling either. It was remarkable the ease of which the Gunners broke forward at pace, despite Chelsea having two of the finest defensive-minded midfielders on the pitch.
