A few Conference clubs may be looking over their shoulders as This is Nottingham reports that "Forest loanee Nicky Shorey could be in trouble with FIFA because he has played for three clubs this season. The world body are unhappy that English football continues to provide a loophole to avoid their transfer rules, which state that players can represent a maximum of two clubs in one season. The former England full back played for Fulham against Portsmouth on Wednesday after signing on loan from Aston Villa, following an earlier nine-game spell at Nottingham Forest. But Shorey and Fulham are backed by the FA, the Premier League and the Football League, all of whom classify his time at Forest as an emergency loan".
I wonder who/what that refers to
