I woldn't say he bottles it even if Napoli doesn't win it. Before the season started, they were never considered above Inter, Gobbi and Milan in regard of Scudetto race, but things have changed while season was/is ongoing. Scudetto it's still Inter's to lose, and it would be scandalous if that's happening for real.
Napoli missing mid-week matches is a bonus for them, but realistically they aren't same level as Inter yet.
Conte just arrived, and he's doing fine given circumstances. This Napoli squad was mentally broken though.
