It’s been pretty sensational when you compare to every England manager post 1966. Blew the chance of a generation at the Euros. Fear it could be 20 years + until England get an opportunity like that again but Italy worthy winners.
England having some sort of incredible squad or golden generation is a myth for me. Fair play to him for how well he’s done.
England's overall talent is incredible, but they're one of those countries where the talent is really poorly distributed. No #8 type midfielders like a Modric, Brozovic, Kimmich, Verrati, Koke, Gundogan or Eriksen who can run a game from there, no great CBs and the star striker doesn't seem to fit well with the wingers around him.
You could literally have England's 5 best #10s (Let's say Mount, Maddison, Grealish, Foden and Gallagher) or 5 best wingers (Let's say Sterling, Foden, Grealish, Saka, Bowen) swapped out for one of those above #8s or a top CB like Van Dijk, Varane (if healthy for a month), Lucas Hernandez or Lisandro or and the team would be better off even having to start say an Eze or Jack Harrison as a 10 or winger.
That happens in international football, and teams like Croatia post-Suker often have one bogey spot, but England have had 2 in their spine since the Terry/Rio/Campbell/King era at CB and in midfield for as long as I've been alive, despite having Paul Scholes and Gerrard (who sure was flawed as a #8, but you could make it work with the right setup, like he would have been pretty great for Germany, right?).
As for Southgate, it's probably what it seems. He's not a good manager but he's not totally incompetent or anything and he's gotten very good results. Like Ole for a while. Probably deserves a Championship job but not a Premiership one. As a Canadian, I wouldn't want him to replace Herdman when he inevitably leaves us for a bigger job.
I think in International Football stability is probably overrated. If I was the director of the FA I'd have called Tuchel the day after his firing even if it would have caused a shitstorm. Mount, James, Chilwell and Sterling is 4 current first choice players (maybe Shaw over Chilwell but it'll be about their form as they're both very up and down) who have worked with him and Chelsea's problem was forward play and you have Harry Kane so that might be half fixed right there.
