When Marotta came out and said we were looking to sign champions, players of great quality, and the hint towards Aguero, we were all expecting great things. That coupled with the daily input of optimism from various sources on this thread has built many of our hopes up far too high, therefore signing Rossi comes as a great disappointment to a lot of people here, it's completely understandable.
That said, Rossi is still a very good player, but we at this moment in time we are looking for DP's heir, and he is not it.
