Obviously I would much rather get Vlahovic. But we cannot afford that, so we may need to take a bit of a punt.
Scamacca looks like a promising young CF who could really benefit from building some muscle and improving his end product. Its very hard to judge him from his career so far - playing as CF for a small team where you will have a lot of space to attack requires very different set of skills than playing for a big team against small teams who sit back. That said, Scamacca seems to have the entire package apart from the above two things in bold, which are understandable for his age.
Inter is also a great place for a CF, historically too but definitely right now. Our team is set up to create chances after chances for the CF. There is a reason why Dzeko, Lukaku, Icardi, etc have done well here compared to their clubs immediately before or after. So this is a role where Inter could take a punt on a promising CF who has all the right ingredients... if he can achieve his potential anywhere, its here.
Yes, we still don't know whether Scamacca is the next Vieri or the next Acquafresca. And apart from that, my other issue with Scamacca is that he will need a year or two to grow into this role at a top club, something perhaps we cannot afford. But that said, he looks promising. Its a tough one, looking at the options available, I wouldn't mind if Inter too the punt. But if we have to take this punt, lets not wait till the summer.
