Robb was a noted winger when he was playing as an 18 year old for Finchley and he signed amateur forms with Spurs in 1944.  Despite the opening to develop his career as a professional player, George spent nine years at Finchley while training to be a school-teacher, where his reputation grew to get recognition with 18 caps for the amateur England side.

As part of the team Rowe was putting together after the two title winning seasons, he realised the Robb's pace in the flank would give him options on how to play opposition teams.  He nagged the player to sign into the professional game, but it was only when Les Medley left at the end of the 1952-53 season that George signed as a pro.

Linking up with Eddie Baily, he formed a good understanding of when to go forward and when to cover for his team-mate, being a willing runner both going forward and tracking back in defence.  He could play the ball off both feet and his crossing was accurate to feed the centre-forwards, having made space to put the ball in by jinking past his marker or just beating him for sheer pace.

In September 1953, Robb was selected to play for the Football League side against the League of Ireland, with his performance doing enough to make his place in the full England side for the first time a reality when Hungary saw off England at Wembley 6-3, leaving him part of a side embarrassed by the "Mighty Magyars."  Unfortunately, that was his only senior cap, but he did play three England B internationals before the end of the season.

Knuckling down to his club career, George played a major part in the transitional years between Rowe's push-and-run side and the new era that Bill Nicholson was to herald after he took over as manager.  His service to the club during that time was unstinting and he played on until a serious injury in 1958 forced him to retire in May 1960, leaving him to fall back on the training he did as an amateur, when he returned to teaching.
