I think recruiting Rudi Garcia was not the right choice because, although Rudi Garcia has also been or had been head coach at big teams such as Lille, AS Roma, Marsellie, Lyon and most recently Al-Nassr. But it seems to me that Rudi Garcia has not had a great run with those teams and as such, I personally would doubt Rudi Garcia's quality at Napoli. Therefore, it is certainly difficult for Napoli to be able to get a stable performance next season and I think Napoli's chances in the Champions League are not very good because of changes like this.
I think so but the problem is napoli the only party who knew the exact reason to recruit garcia after he has been sacked by nassr. Some clubs are trying to make its club even better like real madrid, intermilan, even PSG and manchester city. Napoli's chance in UCL is quite small at this moment. It can be seen from how even manchester city buy some world class quality players in summer. Napoli was signing a coach that has no good track record. he has been coached lille, roma or even marseille but has he ever god a prestigious trophy before? That's why napoli was signing a bad coach for the club. In my opinion that if this time, napoli may not able to defend its scudetto.
Garcia never make its club won scudetto in the past. Roma has been runner up for two seasons but this club was not winning the scudetto. That's very bad decision to sack him as his performance with al nassr can be considered as a reliable proof if he has no capability to handle the club even in the saudi pro league as well.
