If Napoli wants to fire Rudi Garcia, I think it will likely be a blunder for them because we often see teams that frequently change coaches and certainly won't be able to make many changes in the near future. However, that is up to the Napoli owner because if he is not satisfied with Rudi Garcia performance, he could fire Rudi Garcia if Napoli loses again in the next match.
There will need to be more adaptation if Napoli changes to a new coach, but if in the next match Napoli loses against another team, I think also Garcia position will be very threatened at there. Because the next match is against Verona and it would be very unworthy if Napoli lost, but I don't think Napoli will lose anyway. Verona is not a strong team on paper and Napoli should be able to win perfectly, although they are playing away.
