With Mourinho, Guardiola, Klopp, Conte and Wenger the Premier League has without a doubt become the most competitive and watchable league in the world. But when you see the likes of Barcelona, Real Madrid and Dortmund during their games, the gulf in class is almost embarrassing. The Premier League teams are nowhere close to that level. With such teams being managed by far less experienced managers such as Luis Enrique, Zidane and Tuchel, one can't help but wonder how big really is the role of a manager? Maybe it's just having a good enough personality to act as an enabler between great players in a squad.
