No reason at all why he shouldn't pass 100 England caps which would really cement him as one of the all-time legendary English players.
76 caps now, unless the manager wants to unnecessarily rotate keepers, should get all 4 remaining qualifying games and get hopefully at least 5 during the World Cup as the team will surely get through to last 16.
Takes him to at least 85 caps by this time next year, by which time he'll only be 32 and probably have at least 4-5 years left at his prime.
Probably got one more tournament in him as first choice unless something goes badly wrong, so with friendlies and qualifying, obviously plus the tournament itself in 2028, loads more caps to be had.
Chilton 125 caps
Rooney 120 caps
Beckham 115 caps
Gerrard 114 caps
Bobby Moore 108
Can easily get in and amongst that list.
