Which soccer player of the post-war era played 764 games, all for one
club, plus 48 for England?

Hi dionysius3,

The player is Jimmy Dickinson.

"Jimmy Dickinson holds a unique place in Pompey history. Many famous
names in soccer have served their clubs with distinction and
dedication but surely the most distinguished and loyal of all was
'Gentleman Jim.' He was one of the great names in football during the
game's golden age after World War Two when crowds flocked back to
soccer in their millions."
(...)
"His sound, consistent and unobtrusive performances earned him England
recognition too - a total of 48 appearances for his country made him
Pompey's most capped player of all time. More significantly he played
764 league games for Pompey - a record for one player at a single club
which was not broken until Swindon's John Trollope went six better in
1980."
