I do not know the disagreement between the President of Napoli and former Napoli coach Luciano Spalletti because he left the club just too soon.
He had a good understanding with his players which he failed the first season with only for Ac Milan to come from behind and win the Seria A.
So far Conte has been silent about any of the offers we have read given to him as a replacement for Rudi Garcia. So far Garcia remains but it is clear Napoli management are on the look out for his replacement.
I think they made a very big mistake by allowing Luciano Spalletti resign from his managerial role in the club without persuading him to stay or sorting out any issues they had to keep him in the club, it's just like City letting Pep Guardiola leave and signing Potter or Lampard as his replacement, It's never going to work or even helped the team move forward rather it would even destroy the good records Pep has kept for the club, Rudi Garcia wasn't the rightful person for the job and I'm still wondering what made them to pick I'm as a replacement for Spalletti.
They need to do away with Rudi Garcia immediately if they want to secure a champions league position this season cause not qualifying would drag the club backwards and they'll be forced to sell some of their key players to clubs that would offer them champions league football.
