We all know Jose Mourinho is not a coach to stay jobless and without a team for a long time, he usually gets interesting offers and even if they fired him from Roma but still, he is still close to joining another team.
Mourinho's agent, Jorge Mendes started talking about this coach with Aurelio De Laurentiis and there is a high possibility of seeing an agreement between Aurelio De Laurentiis and Mourinho which means Mourinho can be the next coach for Napoli.
Since they lost Luciano Spalletti they couldn't find a good coach and maybe Mourinho can save them from this situation.

I really believe that Mourinho will not take over the coach position of Napoli. Because I don't need to be a coach or an expert to see that Napoli will continue to fall down. They will lose their star players in the next summer or two more seasons so if Mourinho joins Napoli, he will have to rebuild that club from nearly beginning. Even Napoli can spend more money for transfer market than Roma, it is not a situation Mourinho wants to be in.
Rumor is Mourinho is waiting for an offer from Newcastle United to return to Premier League and I see it is a highest bid for his future now.
This could possibly happen if Jose Mourinho still wants to coach another team in Serie A and does not intend to move to another league, if an agreement can be reached by both parties. To be honest, I'm not too sure about the coach that Napoli currently has because after firing Rudi Garcia and replacing him with Walter Mazzari, Napoli continues to experience decline, not improvement, Napoli fans are very worried about Napoli's current performance, especially when facing the last 16 of the Champions League and their opponents are quite I really think Jose Mourinho could be a good choice considering he has more experience than Mazzari.
In fact, I doubt that Jose Mourinho will be well received by Premier League clubs because Jose Mourinho's coaching system looks old school and the strategy used for the strongest league feels like it will be impossible to compete easily, previously he was sacked by Chelsea and Manchester United so I think waiting for Newcastle to appoint him as coach is still quite doubtful.
