If you have spent time with Jose Rafa and Conte you are going to be one boring pragmatic fucker.
Add in a boring bearded waistcoat wearing dullard wanker who was a centre half for Middlesbrough and holy dull shit Batman springs to mind.
But there's always a misconception that Mourinho always had boring teams, which isn't the case at all.
he actually had some very good teams that scored a lot of goals but he still knew how to set up a team to be pragmatic and defend well while having the firepower to actually becomes successful. That's why he was good.
The problem is lesser managers only take part of that approach and thinking being pragmatic brings success but often not the case because you still have to go and beat teams too. That's where Southgate and Holland fell short in the world cup semi and the euro final and lost winning positions.
A successful manager like Mourinho would have succeeded from a winning position in at least one of those games. Even if he was pragmatic, he still has a room full of trophies because managers like that also know how to put teams to bed.
