Of course not, but I share the opinion that this game was approached in a very weird way by Walter Mazzari. I don't know if this was incompetence by him or underestimation at its best, but how can a team like Napoli underestimate another team from Serie A. It is not like they played against a team from the Serie B or worse than that when it happens that the far superior favorite underestimates how hard it can be to beat those teams. Take Bayern as an example when they played against a 3. Bundesliga team and lost, but nobody would ever say that was on purpose. If that were true, the coach would get sacked immediately.
Shocking to see Napoli losing 4 nil to Frosinone and not been able to maintain consistent performance in the Seria A matches. Could it be that all these unplanned negative results happens because Luciano Spalleti steps down from managing the club? Though he resign and I'm confident Napoli will bounce back to winning matches but it will take lengthy period because we can never be too sure of these matches. Napoli headcoach,Walter Mazzarri have learnt his lesson and he will not give room for any poor performance from his team, he's aiming for the best spot on the table.
I think they are all-in for UCL this year and the fact that they qualify further again , makes me thinks that both Serie A and especially the cup can wait a bit longer or not waiting at all ( being already eliminated from cup ). I'm sure they will focus a lot in the second part of Serie A season but personally I don't expect them to produce magic like they did last year but I do see them achieving quarter finals in UCL.
