Five years is a long time mate.
We only have to see the emergence of Foden and Bellingham to see things can change very quickly in what comes on to the scene.
Yes but look at every world cup squad England ever send to a competition.
2018 - Ashley Young and Cahill were about 32/33.
2014 - Lampard and Gerrard were 34 and 35.
2010 - Heskey, Carragher.
There's always a couple of older heads who've been around for a decade. Out of the current group most will be long gone. Kane would be 33 but I'm convinced his ankle will be dust by then.
It's probably Stones and Sterling. They might not be starting, but they'll be around the set up because they'll have been to half a dozen tournaments.
Also Sterling's form for England recently is incredible. 12 goals and 10 assists in 16 games, its about 40% of Englands goals when he plays. Southgate trusts him, I think he's probably going to start the first game at the Euro's so I don't see him worrying about his England place.
