Milan vs Napoli match which will be 50:50. that's because before Napoli could be superior to Milan, but in the previous meeting Napoli were destroyed 0-4. this makes the fight will take place unpredictable. both are pretty even.
but for Madrid vs Chelsea. I don't think Madrid will suffer. at least in the first leg Madrid will win. and in the second leg they will only defend. although I know, sometimes matches in the Champions League are very difficult to predict.
why it's not easy to guess because now the UCL has reached the quarter-finals and maybe if it's in the group stage it's still predictable, but for the quarter-finals to the final it will be difficult because all the clubs that qualify always have the opportunity to surprise, just look at yesterday everyone thought that in the league match Napoli could beat Milan, it turned out that Napoli was beaten with a score of 4 goals without reply and that is what makes predictions still difficult, talking about Chelsea, who just left Potter because he was fired, of course it can also have other effects for Chelsea's game later, no sure they qualify to beat madrid who are currently in good form
That's right, anything can still happen for all the teams in the quaterfinals. But for Milan vs Napoli, I'm pretty sure Napoli will get rid of Milan in that match, regardless of the results in the domestic league I don't really think about it because it will definitely happen in the domestic league, moreover Napoli always win consecutive wins there will definitely be times when they lose the match league. But for the UCL match Napoli will give everything to get the best results in the two legs.
For Chelsea, although previously there was bad news about the sacking of Graham Potter, it seems that now they have a new coach until this season ends, namely Frank Lampard. In fact, Lampard has been a Chelsea coach, but the results achieved were not satisfactory so he was sacked in 2021. Even so, Chelsea's opponent is Real Madrid and in my opinion there will be no other team including Chelsea who can get rid of Real Madrid in this round. So it's clear here that Real Madrid will very easily get rid of Chelsea in the quarter final.
