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.
of course in this case I can not conclude how capable the Serie A teams are because of course sometimes Inter Milan, Napoli, Juventus and Atalanta can surprise the world if they are great teams and of course it is no stranger in the world of football that surprises always happen and in the last season Inter Milan was not favored because their strength was declining but finally a surprise happened and finally Inter Milan was able to reach the final.
but yes indeed when compared to now of course I also have the same thoughts as you if Napoli, Inter Milan and Atalanta will certainly find it difficult to beat the strength of Manchester City, Liverpool, Barcelona, PSG, and Munich and of course the teams from Serie A will have the potential to find it difficult to win the trophy.
it is true that Napoli of course they are currently building a squad seriously and of course with the arrival of De Bruyne of course it will have a positive impact on Napoli. but when compared to Real Madrid and Barcelona, Napoli is still less competitive because Real Madrid continues to improve its team and bring in quality young players and Barcelona is also like that, especially with Nico coming to Barcelona as a new player, it will certainly make Barcelona even stronger. and it is true that now the team trained by Hansi Flick is indeed good.
But yes, this is all just speculation and of course we don't know what will happen later and of course there is still time for all clubs to improve their clubs and also bring in new players.
The chances of seeing an Italian side in the finals of the UCL come next season is very possible because the Italian clubs seem to be very consistent although they tend to find it difficult to replicate their previous achievements, last season inter Milan came very close to winning the trophy after eliminating Barcelona but couldn't engage the same energy which they engaged against Barca when they met PSG in the finals and this has always been the case with Italian clubs over the last decades.
