I'm really surprised to find he only won 28 caps.
Yes, his England career was pretty short - primarily because Ramsey prefered Alan Mullery in the central/holding midfield role subsequently.
He went to MExico in 1970, but never got a kick. And that ws very much that.
Ramsey was very good at picking players to do 'a job' - something that Jack Charlton carried forward.
I remember JC recounting the time when Ramsey picked him for England and Chalrlton asked him:
'Why have you picked me'?
'I don't always pick the best players, but try to pick the best team.'
Only three left now from that team -[possibly even the squad, but I can't be bothered to look
] - George Cohen, Bobby Charlton and Geoff Hurst.
