well IF it´s true i think we will have to wait until the end of the transfer window to really judge the transfer.
94m is an insane amout of money but there was a lot of talk about other deals with napoli later in the window to basically make it a players + cash deal and allow napoli to save face.
furthermore, there might be a fixed percentage for the player which he (partly) waivers.
lastly, i think he will fit like a glove
