I will not criticize Lazio's performance, but Como's performance was very impressive, they were able to control the match quite significantly so that Lazio could not do anything and it cannot be denied that Fabregas played an important role in making strategies that made Como like they are now and after seeing their performance I am sure what Como did last season will continue and can even be better.
Spending that much money must have made them really good. They are still not title winner level of a team, but they are looking more and more like a team that can force their way into top four. If they somehow figure out a way to finish fourth, that would be huge. I have Napoli, Inter and Juventus as my first three, but I am not sure who will be fourth.
We have Roma, who looks great, we have Atalanta who was great but not so sure anymore, and we have Milan trying to get back to being great again, and some more, so Como will have hard time. But they are on the right path and building a good team. Just having money doesn't make you good, because you also need to learn to use that money to get better, look at United, they spend 200+ million every year and still suck.
