The coach on a team is like a spear sharpener so that if the coach can fix all the shortcomings of the team then the team will become a team to be feared.
If Napoli has a coach who has experience winning the UCL more than 1 time, then it is possible that Napoli can also win the UCL, but they still have to be supported by reliable players so that the coach's hard work to improve a team is not.
In the last 2 seasons Napoli have played quite well and some of their players have had a number of proud achievements so if in the future they can develop even better then there is a high probability that there will be a chance to win the UCL.
True, that's why osimhen was rejecting galtier to be one of candidate for the next coach of napoli. In my opinion if osimhen wants napoli to hire a great coach that has a very good track record in UCL. It seems like that napoli has UCL as become the main target next season.
I do undertand caused by napoli has been winning scudetto and it was aiming to get higher trophy than it which is UCL. UCL is the most difficult trophy to be won by napoli. it's cuased by there will always be so many great teams participated in the UCL.
That's why hiring a good coach is a must for napoli to make sure its club will able to win it.
I hope that if napoli will able to sign a new coach that has ever won UCL a few times. that will make napoli feels a bit easier to compete in UCL caused by this kind of coach knew the atmosphere in the UCL.
Napoli was failed in UCL last season caused by it doesn't have consistently and strong mentality. That must be fixed as soon as possible by signing a good coach to handle the club.
