I guess he's done some good things like bringing squad unity and creating a good vibe around the camp. I can't stand him as a manager though. People say about Saka being a good decision over the others, and it was, but we all know the reason he went for Saka is that he played a bit at left-back for a while, and that's extremely attractive to a manager like Southgate, who generally picks the team based on the ability to shut down the other team. The fact he is so determined to keep Henderson around is pretty annoying, it's basically because he "is a good leader in the group" or similar Southgate logic.
With Southgate, I feel like it's watching a kid on an arcade machine, there's no coin been inserted so the game's on demo mode, but the kid thinks he is controlling it. This is what I think Southgate is doing. The team is full of genuinely top-drawer players who are coached by much better managers week in, week out. So it is not too hard to beat significantly weaker teams. When it comes to crunch time, Southgate still manages to find a way to snatch defeat from the jaws of victory - time and time again. The Italy final in particular should have seen him sacked. And any national team with some vestige of pride in their football would have hounded him out after that. No way the likes of Spain, Brazil, Argentina put up with that damp squib of a management showing in the best-ever chance to break a 60 (or however long it is) year duck, in a home stadium, against a crap Italy (regardless what anyone says, look at their qualifying record after).
People who say "second most successful England manager EVER!" can sod off. You can't compare national teams over decades like that, disregarding the mammoth amounts of money that have gone into premier league academies in the last couple of decades (as well as home-grown quotas etc) ramping up the quality level of our domestic players. I wonder how GS would have fared with the WC2010 squad. I think we all know the answer to that one.
