The official site doesn't say what we actually got so it might be more for Zalayeta. Some sites say 3m for Zala's ½ and 2.5m for Blasi's. UNOFICIAL
I don't know why most of you are so sad and think that this transfer is so bad. We get between 4 to 5.5 m EUR (differents sites different informations)for half Zala and Blasi. If they don't have success, then we could get them back for less, but if they have a great year we could sell the other half of them even for more then 4m EUR.
We think that Zala is good, but he was actually our fifth player also in seria B, so who would be prepared to give as more money. But if he will have a very good season and if he score 10 - 15 goals, then his price will go up and Napoli will have to give us more then 5 m for the second half. So IMO this is not such a bad transfer. Maybe we should just sell Blasi, but probably our management just speculating that if he also have a good season they could get more for him then they could get at this moment.
