Shaq Coulthirst's goal was enough to see off Cheltenham 1-0 last night to book a fourth round derby at West Ham in the FA Youth Cup.
Coulthirst was put through one-on-one in the 29th minute and the striker made no mistake, slotting low past Robins' goalkeeper Dale Reaney.
Tottenham's goal sparked a purple patch in the first half that could have put the tie beyond doubt, but the home team stuck to their task and could have had an equaliser in the second period were it not for Luke McGee making some fine saves.
Spurs now face an away trip to the Hammers in the fourth round, to be played by January 19.
