Melo is a good player that we shouldn't even sell. Secco got us a good player. He dearly overpaid, but he did get us a good player that shouldn't be sold. Also, his wages match his quality, so they aren't high.
But when someone gifts Melo on loan for miserable 1.5m euro, then Melo becomes that guy's mess.
If Marotta sells Buffon for 6 million euro, I surely won't blame Moggi for signing Buffon for ~50 mil.
