In addition, Napoli is also doing quite massive signing in this transfer market to defend the Scudetto title. Some other players they are eyeing are: Yunus Musah, Borja Sainz, Oumar Solet, and several other players on the list.
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.
They see his achievements, see KDB's ability as one of the smart players especially on the field, as a creative and smart playmaker to open up opportunities. Although previously at Man City, his performance declined due to several injuries and also internal problems, but now, at Napoli, his role will certainly be crucial, with his ability, maybe it won't be as optimal as before, but it won't be bad. He is a professional player for at least the next 2 years, he is still very valuable and has high potential.
