Højlund is going to be Napoli's main CF in the absence of Lukaku. His return will probably be no earlier than mid December for now.
I don't think so, in Napoli's latest match, Lukaku was not in the squad, instead of playing Højlund, Conte preferred Lorenzo Lucca as a starter. Napoli's next match is against Fiorentina & it's not impossible that he'll feature in that crucial clash. It would also be an opportunity for him to prove to Conte that he belongs at Napoli. But back to my initial thoughts, I'm not sure Højlund will play. It might take some time for Conte to get him back into the side.
I think you have a point mate, playing Fiorentina is always a difficult match for Napoli even though they mostly comes out victorious. In there last game we all saw how Napoli struggle to get a win until the very last minute of the game, so bringing a new player who is yet to blend with other player and blend with his style of play will be very difficult. Hojlund is a good player but every manage have a way in which they play and they also needs to teach the player how they they want them to play so I still think against fiorentina florenzo Lucca will start then Hojlund give some minutes off the bench. I really want him to do well at Napoli.
