In addition, in a team to win a trophy depends on players who have the desire, experience, and mentality to win a trophy. So Conte saw that in De Bruyne and he rejected the offer from the Saudi Arabian team because he still wanted to play in the Champions League. So with that desire it will certainly produce good performance for Napoli next season. In fact, I think Napoli is very lucky to get a midfielder like De Bruyne, especially for free.
In Serie-A itself, De Bruyne's presence will have a significant impact on Napoli because now they have a creative midfielder who can help the attack line become more dangerous. De Bruyne is known as one of the midfielders who has the ability to provide accurate passes and he is able to play as one of the midfielders who controls the course of the match so Conte feels quite lucky to have him.
If we talk about competition in the Champions League, maybe De Bruyne himself is not able to give his best if not supported by a number of other experienced players because the Champions League has much tougher competition. I think Conte needs to find some other players if he wants to compete there and maybe the defense line is also very important.
