For involvement until the semi-finals I agree but to go to the final and win the trophy I am a little doubtful. Now if you look at it, only Napoli are probably so busy in the transfer market and they are looking for experienced players who are no longer young. But there is a weakness in this strategy because players who are quite old will be quite tired when facing teams filled with young players. Like for example when Inter Milan faced Barcelona or PSG because even though Inter Milan managed to beat Barcelona we could see a number of their players were tired.
I don't want to speculate further on the chances of the Italian team, Inter Milan will also have a hard time repeating their success in appearing in the final after Inzaghi's departure. I also doubt the ability of Juventus, Napoli and Atalanta to compete with teams like Liverpool, Man City, Real Madrid, Barcelona, Munich and PSG, even though they are able to make a surprise, their chances of winning the trophy are very small.

Yes, Napoli are very serious about adding depth to their squad after winning the Scudetto, but when they appear in the UCL, their strength is still below the level of several other top teams. Real Madrid are also rejuvenating their squad by bringing in quality young players, Barcelona young players are also maturing under Hansi Flick and the arrival of several new players will further increase their strength.
