Romelu Lukaku's could be facing a long term injury which will be a major set back for Napoli in the season ahead. They better accept their fate, act fast and get his replacement before the end of the transfer window. And they also need to consider a perfect striker that will perform more than Lukaku in their games, it's really not certain if Napoli will struggle to win consistently in the coming season. That's only if they could see a perfect striker for the job!
Napoli must have already prepared for a situation like this; I think it's more convenient that a team has a replacement for every player just incase. They had some good performances in their previous games, and I don't think any team in the Italian league be smashing them this month.
