I can't find anything in the FIFA or FA rules that lays down the number of Goalkeepers allowed in Tournaments Is it something you made up for the game?.' I once saw George Farm the Blackpool and Scotland goalkeeper, play centre forward and get a hat trick. Of course he had Stanley Mathews centre-ring the ball. George just nodded them in. If we had a goalkeeper injuring his hand and there were no subs left could he /she not play out?
