The age of 33 still seems to be quite favorable for a short period of time. A good performance history certainly gets him good enough, but for injury history I think Napoli should be wary. They should be able to use De Bruyne well. His long injury history might come back if Napoli are not able to manage him. A 2-year contract is good enough to tie him down for the second year. I think Napoli can take advantage by reselling him. I think many MLS and Arab clubs want him.
I honestly don't know if DeBruyne is a winning move, certainly the fact that he was injured for so long is not very good, you risk taking a broken player who doesn't even play a game for 2 years.
In this case, unfortunately, it's a matter of luck.
Of course Kevin De Bruyne is on the winning track, and you are wrong to say that this broken player has not played a single game in two years. We recently saw the Italian giants complete a high-profile transfer and they were even able to employ this player there. I think this player will be able to reunite with his Belgian teammate Lukaku as a result it is almost certain that the Italian giants will be able to perform even stronger. He was able to show us all his elite playmaking skills in the Premier League, so maybe he can reach that level again in the Italian league. It is true that he is still valuable even though he has already been given a reception upon his arrival in Naples.
I believe KDB would get back to form. Sometimes it's like that in a player's career life, injuries and other things can reduce your form and maybe you need another environment to catch yourself back. Rodri's absence affected all of them at Manchester City and Debruyne had to play more physical and defensive roles against the distribution role he played earlier and I believe they all led to his consistent injuries. I believe he would find his feet at Napoli. It would only take a little while.
