He’s a good manager but not an experienced tactician. He could do with having someone like Wenger as his number 2 to promote a more attacking style - the Yang to his defensive YingStill not convinced Southgate is the man to use these players, he is a good defensive coach but when you have Foden, Grealish, Bellingham etc you need to be playing to your strengths and not sure he can do that.
I think he’s a thoughtful and reflective person so he is more likely to consider a more proactive style than say a staunch, ‘stuck in his ways’ dinosaur like Jose. But a number 2 is a must IMO
