Time for Pickford, Walker, Rice, and Kane to be moved on. Time for the likes of Ramsdale, Trent Alexander-Arnold, Wharton, Palmer, Foden, and Watkins to be considered senior players. Bellingham should be played as a false nine or a deep-lying midfielder and nothing else.
But, crucially, it's time for Southgate to be moved on. He's taken this team as far as he can. He's improved the mood around the England set-up tenfold after the disastrous McClaren/Capello/Hodgson era, and he's laid a good foundation for whoever comes in next, but someone else does need to come in.
