They finally understood that we need to keep this player, I'm glad they've come to their senses and have decided for the best.
This makes me understand that perhaps they have understood that they have made a big mistake with Spalletti.
Napoli's awareness in maintaining Osimhen is something that is very natural because Napoli knows that they still really need a striker like Osimhen to keep themselves strong next season. Regardless of who will train Napoli next season, what is clear is that Napoli must be able to retain and maintain some of their best players this summer so as not to decrease their strength next season. So this is a very, very wise realization for Napoli now.
There's no doubt that he was one of the players who greatly contributed to their Scudetto success last season. And when they keep him, it's a good move, although on the other hand they might lose money on transfer fees if they sell him.
Regarding the figure of a coach, it is possible that it will affect the style of play of a player, it could be better or vice versa. Because after all, a coach must have the ability to read the style of play of a player and then he will adjust the strategy. I won't say that players don't need to adjust to the strategy that a coach wants, but in this case they must understand each other between what the coach wants, and vice versa.
Pressure, criticism will definitely be food for their new coach, if not something with what is expected. Not to compare, but it's something we often see when there is a change like this, especially if the previous coach showed something extraordinary.
