First it was Chelsea, then Tottenham and now Arsenal who have benefited from playing a back three.
It is no coincidence that Arsenal have won six of their seven matches since adopting the system.
Playing three at the back gives you an extra central defender while against Stoke, wing backs Hector Bellerin and Nacho Monreal were particularly threatening going forward.
Managers are like sheep. Now Antonio Conte has become the first boss to win the Premier League with this system, we will see more managers adopting it.
