Except he didn't have much of a CV.
International mangers have a limited field of players to select from and can't buy the ideal players for their system.
So it doesn't matter much if he has a philosophy, if there aren't the players to implement it. They have never been embarrassed and gave everything they could.
And despite Peps talents he still hasn't managed to integrate either Foden or Grealish into centre midfield positions. Something Southgate gets flack for.
I get what you mean about the CV, but there is a lot of context around both that is missing.
The best international managers adapt their philosophy to meet the talents of the players available to them. I'd argue that Southgate has one of the best talent pools to choose from to deliver his philosophy. The issue we have is that nobody knows what his philosophy is.
We haven't been embarrassed in tournaments, but we've been assisted with very kind draws, beating teams we've been expected to beat and losing against the first half-decent team we face.
My issue with Southgate has always been that he has no tactical nous and he can't make decisions that change a game, and between evenly matched teams at international level that makes the difference. The game against the USA was proof, if any further evidence was required, about his limitations.
To your last point Pep doesn't need to integrate Foden or Grealish into midfield as we have KDB, Bernardo and Gundogan there.
I'd compare wanting to play Foden in the middle/10 role to that of France, and Deschamps seeing a lack of creativity in the middle of the park and tasking Griezmann to take on that responsibility.
If you watch the game back, at around 40mins Foden moves centrally and France shit themselves, a couple of minutes later he drops deep and you can see the panic in Giroud not knowing whether to pick him up or not.
