@LABoog4 I don't quite agree on your assumption about England. When you have four good attackers, it does not make a good team: those attackers still need to receive useful balls, so unless you get better ball handling from the back, the problem will remain the same. How many times do Walker, Stones, Guehi, Trippier, Rice, Alexander-Arnold or Gallagher really give a good, useful pass forward?
I don't think Southgate is the problem, I think Southgate is preventing worse. The current 4-2-3-1 is the only system where those front four fit in, thus making the system around them is exactly what happened and is exactly what is going wrong for England. But the way Southgate makes them play the system at least gives them stability at the back. Not losing can get you very far into a tournament.
The system is a copy from the Netherlands 2008-2012 period, where essentially six defend and a quartet of attackers up front, free to do whatever they want. The difference is that Heitinga, Van Bronckhorst, or Van Bommel had considerable more ball handling talent, than Stones, Trippier or Rice do today for England. And somehow, that ball needs to get up front for Kane to hammer it in.
My solution would be going back to that 5-3-2 wingback system they used before and brought them 3rd place in the world cup and a final in the last EURO. Because then, you actually get those players at the back in their strength: power, speed, stamina. It is less reliant on a good, quick-paced passing game. It does however mean you have to sacrifice one of those front four players: Bellingham behind Kane, who is coupled with either Saka, or either Foden, or players of that type (Sterling, Graelish etc)
