I think we really, really need Aguero, not just from a sporting perspective. We need to signal to the football world (and other players) that we are still a force and that we can still get world class players. WE might get a slightly worse player for a lot less money, but we need to show that we can still get the world superstars or potential superstars, that we can get any player that other Italian clubs can get, otherwise we risk losing our appeal and it will be harder and harder to attract world class players.
We've missed out on the CL two years in a row, we have had pathetic play in the past two years, this is perhaps our last chance to show that we can be the old Juventus.
