That's a serious indirect sign for Lukaku who is playing with the nerves of Inter management and fans! It will be an awkward moment for him to see Inter rejecting him, Juventus neglecting him and absolutely out of the strategy of Chelsea 
Lukaku is like a Judas by doing that. He betrayed all trust of Inter Milan and love of their fans for him recent years and in this summer. It is surely time wasting for Inter Milan when they tried to negotiate with Chelsea for a transfer of Lukaku to their club but behind the scene, the player and his representatives had some talks with AC Milan and Juventus.We can't jump to conclusions and doubt him just because he's a newcomer we should at least give him a chance at least until mid-season
Rudi Garcia already has experience in several leagues his abilities can be applied in any team including Napoli I have no doubt about that
Moreover, Napoli still uses the same team composition so Rudi Garcia just needs to continue domination and strategy.
He is a new comer in Napoli but he is not new in Serie A. In the past he was a coach of AS Roma and had some good seasons with Roma. He has enough experience in Serie A which will help him to have less difficulty for their management job in Napoli but he will have to mitigate effects from transfers of Napoli star players in this summer. Losing star players and attaching new players to a squad together are difficult task for Rudi Garcia.Rudi Garcia already has experience in several leagues his abilities can be applied in any team including Napoli I have no doubt about that

I see if they can end a next season in top four, it will be an acceptable result for Napoli and Rudi Garcia.
It is too ahead of schedule to decide on the future of the newly appointed manager. He should be given enough ample opportunity to assess whether he would be a good short-term or long-term coach for the club. Rudi Garcia should be given a chance before proclaiming that he is unfit to lead Napoli to victory in Serie A. We all know what happened to Napoli; of course, they've been highly competitive for the scudetto for quite some time; the club winning it last season was completely unsurprising, because we all expected them to win it, albeit after a more difficult work out by the coach and his squad.
At Napoli, they usually don't have too long-term plan with their coaches. Their President Aurelio De Laurentiis does not want to have long term plans with coaches or he just does not have enough patience to complete such plans. Many coaches came and went away in Laurentiis era as their club president and I really believe that Rudi Garcia will not be different.If Laurentiis did not keep Spaletti after a great successful season, how will he has enough patience to keep Rudi Garcia in Napoli if results are worse than his expectation?
