Lol, very funny. If a head coach doesn't make any changes, but why would the team sell some key players? After all, even if the coach doesn't make changes, there will always be players leaving and coming in the transfer window. Therefore, it is very inaccurate if you argue like that about, Garcia who made a lot of changes. After all, no team continues to use the exact same players as in the previous season. Also, no one can blame Garcia, because basically Napoli do not have the quality to be able to dominate Serie A every season.
Garcia will influence the team in any case because he will use his strategy, he will have his training regime and other habits that can affect the team. Whether this will bring the team a better result or not we will see, but without Spalletti we will most likely see a different Napoli. It is normal that the team may change with the start of the new season. By the way, I can say that Inter worked very well in the off-season and they have an excellent chance of winning the Scudetto this season.
