Pazzini is a good striker. I would not have been opposed to getting him 2 or 3 years ago, but now it doesn't make sense any longer.
Whether or not he's better than Matri is up for debate. But he's clearly no major upgrade, which makes any potential move worthless if you ask me.
Going with the assumption that Pazzini is as good as Matri and would offer the same, then replacing Matri with Pazzini makes sense only if we want Jovetic or some other expensive striker, and we need money to get him.
Something like this:
- We need to pay 25m eur for Jo-Jo but we don't have the money.
- Milan are willing to pay 12m eur for Matri
- Inter don't need Pazzini but they can't sell him
- Juve don't need Krasic but can't sell him. Inter would like to have Krasic (there were reports that they want him)
In that case selling Matri will provide us the needed cash for Jo-Jo and if we exchange Milos for Pazzo we get the replacement for Matri (again, if to Conte Pazzini is at least = Matri).
