Former Scotland manager Craig Brown tells Radio 5 live's Victoria Derbyshire players from Scotland "would be selfish to play" for Team GB at the 2012 Olympics.
Stuart Pearce and Hope Powell have been selected to coach the men's and womne's teams respectively, but Brown reveals he would be "disappointed if any selected Scottish player decided to take part" in the tournament because their participation would damage Scotland's autonomy at FIFA.
It will be the first time since 1960 that a Great Britain football team will take part at the Olympics, yet it remains to be seen if each of the home nations will allow their players to be selected.
