I honestly don't think Southgate is a better manager than Farke.
Trent as a 6 is dreadful. Sure, his passing range is world class, but out of possession or with his back to goal, he's clueless. Mainoo or Wharton should be in there. They're young, but they're exactly the type of profile of midfielder you need next to rice.
One thing that hasn't been talked about enough, which I think is really harming England's build up is Pickford. He goes long 90% of the time and the ball just keeps coming back and England gradually drop deeper. He's never let England down, especially in big moments, but England need to move on from him if they want to be better when they have the ball.
