More than 10 and less than 15, I'd say around 13 or something. If he keeps on playing well and gets picked for Azzurri then his value can defintely grow a few more millions.
that are fan-values ... while in the deal we did he is worth about 6m € and there is no way anyone will say "hey, he played good, he is no worth 15m € and we will give you half of that for the other half you still own".
