Old guard faulter and Young defenders in form
In addition to Cahill's decision, the performances put in by established England cap holders, Chris Smalling and Phil Jones must not have helped their chances in any way, shape or form.
Full backs Kyle Walker and Ashley Young have not had regular game time or starting opportunities, the same is the situation with John Stones of Manchester City.
What this does is open the door for the likes of Joe Gomez, who missed the World Cup due to an injury and has since shown amazing form partnering Van Djik at the heart of the defence for Liverpool. Fellow Red Alexander-Arnold carrying on from last season has the chance to stake his claim as a permanent feature too.
Leicester's Harry Macguire and Tottenham's Keiran Trippier seem to be the ones who have carried on their good form from the summer in Russia, both scoring recently and looking fit and ready to go.
Wildcard: Aaron Wan Bissaka (Crystal Palace)
