Tegal,
Correct me if i am wrong, but if a young player under the age of 21 is offered a new deal but doesn't sign and moves to a "bigger" club, then depending on the estimated future value of the player and appearences for the club the old club will be compensated.I believe this was introduced to stop smaller clubs best young players being poached for nothing. Signing a youth player on a three year contract for example doesn't seem any riskier than signing an overseas player on the same, espeically when i look at Diego and Mulligan who, established pros offered very little to the club but cost alot more.
