The 2018 side featured the banter midfield of Lingard and Dele Alli didn't it come the end? It may not have been an innate cultural reason, but that side wasn't that great.
This current side has some superb players, but many of the England teams over the years have. It also has some glaring inadequacies. Do either of the reserve goalkeepers even get a game for their club? Literally no left back. Sketchy at best in the middle of defence. Better players in attack, maybe, but let's not pretend that the likes of Foden and Saka are light years better than Gascoigne and McManaman. It all comes down to Bellingham, can he be Rooney 2004, without getting injured? That 2004 team was/should have been absolute mustard, although it does feel like we haven't had an actually good goalkeeper for decades, no offence to Pickford who has almost always stood up and been better than expected.
