If I'm on the German analysis team, I'm briefing that you flood the midfield, suffocate supply to the forwards and let Rice and Philips have the ball before swarming them leading to easy turnovers and a chance to run at the backline.
England's forward line aren't performing, but the screws can really be turned by forcing them to go deeper and deeper to assist the midfield. Kane looks sluggish and like he can't keep up with the play, nor is he holding up the ball to play others in, which forces his flankers to do too much. By pressing the midfield, those flanks will have work harder and from deeper to progress the ball, which is exhausting, and once tired, mistakes inevitably creep in.
Germany don't look particularly dangerous - very beatable with the right personnel and strategy, but Southgate won't put out a midfield that can drive the Germans back and negate what I believe will be an easy press. Bellingham and Grealish absolving Rice of anything but the basic, conservative passing he's shown thus far would be my preference, but Southgate is not going to start a game of such magnitude with a 17-year-old CM and I feel his apprehensive nature will give the Germans the midfield and the impetus to really drive a wedge between the supposed connective transition points through the midfield into attack.
This German team are nervy and can be rattled if the pressure is kept on them, but that goes against Southgate's principles and I think it'll play right into their hands. A better manager and I'd go into the game thinking England could really make a mark on the tournament with a statement performance in this game.
