well many player values are based on their potential increase in revenue they bring, becks was the key example. Arguebly ronaldo was also one, as they could have signed a better striker than him if they really wanted to.
john yeah yours counts but a realistic specific number you didnt give. by value i mean the one by which you judge a transfer fee appropriate for a player. 100s of millions...naah. i dont even think hes sold nearly enough jerseys to recuperate that.
