Honestly, I agree with a lot that Southgate just doesn't seem to have it in him to manage a team to a tournament win. Our record against top 10 sides is really woeful, and the 2 tournaments where he got us to a semi and a final, we had very favourable draws.....WC2018 we actually lost all 3 games (Belgiumx2 and Croatia) against half decent teams and drew with Colombia.....Euro 20/21...you can't imagine an easier run to the final than Ukriane and Denmark at a Euros for the quarters and semi....fair play for beating Germany though.
On the flip side though, I look at the squad he has, and whilst the attacking options and midfield options are class.....that back 5....wobbly as ****, no one but Walker has any pace, which means playing a high line is incredibly risky, the keeper has got a permanent blunder in him and at left back it's all a bit meh. He can't just go out and buy new defenders, so maybe that's why he's always played it safe with 2xDMs in centre mid, maybe that's why he has to be a bit more cautious....
England manager, money aside always been a thoroughly thankless task.
