Pioli has returned to Fiorentina for his second stint as coach, after leaving Al Nassr over the summer.
In a recent media preview, he expressed his excitement to be back in Florence and praised Napoli's coach, Antonio Conte, saying he is one of the best in the world.
Pioli acknowledged that Napoli have been very successful in recent years, winning two Scudetti in three years and strengthening their team significantly.
He believes that Napoli are the favourites to win the title again this year and have the potential to compete in the Champions League.
Despite this, Pioli is confident in his team's abilities, saying they have prepared well and are a good team.
He also praised his player Moise Kean, saying he is very strong and has a lot of room for improvement.
