Not just Sporting but Royal Antwerp is also MU's feeder club.. that's why many young player from MU sent to Antwerp like Campbell n Dong Fang Zhao..

Man utd will be able to send player on loan to Sporting and Antwerp as well. Man utd also have first option to buy player from these feeder club. Iy's mean once a bid for a player is accepted by these feeder club, a bid of same value from man utd also be accepted.. Then it's up to the player to decide his future..

I suggest we discuss this on man utd thread.. no need to open a new thread..
