Spalletti gives a very big impact to the performance from napoli but the problem will be coming very soon. So many clubs putting their eyes into the napoli as those clubs may be interested with some starting line up from napoli. That will force spalletti think to get the best rotation when some main players in the current squad will be gone. Spalletti is very happy with the current squad from napoli caused by it was still doing more and more winstreak against another team in serie a.
It seems like that the same trend will continue when napoli will be facing frankfurt which can be considered as a strong opponent. Frankfurt can't be underrated team.
the departure of several players in the main squad will be bad for Napoli. but if Napoli and the squad are currently thinking about trophies, at least they can get the Serie A trophy if they maintain the performance of the current squad.
thinking selling players who are currently bringing them better is a suicide bomb when they haven't found the right replacement.
I hope that this winter Napoli will bring in players to cover their main squad, not sell their players without good calculations.
