Napoli will have to hope that their top striker Victor Osimhen has not not picked up a serious injury on international duty because he is to undergo an injury scan for what looked like a hamstring injury. If Victor Osimhen picks up a serious long term injury that forces him to be absent for Napoli, the will really feel the effect both in the Italian league, in their first game after the international break against and in their champions league game against Union Berlin. Napoli are not in a good position on the table, every win will be important for them.
Of course, without Osimhen Napoli will have difficulty to get winning in every match, because they lost their goal machine. But hopefully he doesn't suffer a serious injury and remains fit to be able to compete in Serie A and in the UCL. In the match against Verona, I think Napoli should still be able to win without Osimhen, but in the match against Union Berlin they need Osimhen services. Because that match will also held in Berlin, and maybe the home team can perform optimally in front of their fans.
