Yesterday they showed the same drive and hunger we had two years ago, but IMO they made one beginners mistake even before the season strated: they talked about winning Scudetto. Conte was wise in this two years ago, he never talked about it even when we were one point behind Milan or level on points with them. He always used phrases like "we have a long-term project", or " we are still rebuilding the team" and always repeated how Milan are much stronger then us. But he never talked about the Scudetto race. In that way he was relieving the team of the pressure. In the end, it paid off.
IMO this lack of humbleness, along with weak defence and short bench (quality wise), will lead Napoli to another 2nd place finish.
