Not a big deal for them, their only objective is to win the Scudetto, and having no cups is a better thing.
This is proven by they team they choosen to play with this evening, a lot of second choice players.
This game was impressive by Napoli and I think this makes them the favorite for the title in Serie A as well if they can retain this level of gameplay. I watched the game partially and it was one-sided, which I never thought would be the case. I thought Napoli would at least be halfway on eye-level with them, but Lazio could have won the game like 5-1. That was quite impressive and a serious statement made by Lazio to everyone. What a solid performance against their toughest competitor. It was the Coppa now, but I don't see why they wouldn't be able to play the same in the league games.
