I am not sure but he had some good seasons with AS Roma in the past and from their coach record, they have kind of similarities.
Now under the new coach Rudi Garcia, of course, there will be many challenges that he will have to face in carrying out his duties as Napoli coach. Because defending the Scudetto is much more difficult than chasing it, and I think it is not easy for Rudi Garcia to match Spalletti let alone to achieve success in the champions league. This is the biggest challenge for Rudi Garcia this season, so far he has always used a 4-3-3 formation. It will be interesting to wait to see if he can maintain Napoli's track record as a team that is active and looks to attack.
But there is an interesting thing from Spalletti by Rudi Garcia, when Rudi Garcia coached AS Roma he succeeded twice in bringing As Roma to be runners up in the league, but after As Roma's performance declined he was replaced by Luciano Spalletti and now the situation has reversed Rudi Garcia who replaced Luciano Spalletti at Napoli but Napoli's current condition is the defending champion of the Serie A league.
