But Barcelona is still better than Napoli this season. Just look at Napoli who are still slumped in 7th place in Serie A. Meanwhile Barcelona still looks good at 3rd place in Laliga. And to stay in 3rd place in Laliga is not an easy thing. So Barcelona might be the favorite. And for the Inter Milan vs Atletico Madrid match, I won't be confused by this one. Because Inter Milan is currently in their best condition, even exceeding their performance last season. They also just managed to beat Juventus and put Inter Milan at the top of Serie A. And this shows that Inter Milan is better prepared to get through the round of 16. I'm sure of it.
Based on the calculation of points earned in the domestic league, Barcelona is better than Napoli, but overall, both teams are not at their best. Inter Milan are in top form, they are very obsessed with returning to the final and winning the UCL trophy after failing in the final last season. You also shouldn't underestimate Atletico Madrid, this team just held Real Madrid to a draw in La Liga, Simeone team also embarrassed Real Madrid in the Copa Del Rey with a landslide score of 4-2. Inter are better prepared to advance to the next round judging by their performance, but Atletico will try to knock Inter out quicker with their aggressive displays this season.
You are right. I forgot about Atletico Madrid who also beat Real Madrid this season. And yes, this can indeed provide a big picture that Atletico Madrid cannot be underestimated. But I remain confident in the performance of Inter Milan, who are still the best team in Serie A this season. And as you said, Inter Milan has strong drive and motivation to reach the top of the UCL final again. But yeah, Inter Milan won't have an easy match. So losing or winning probably won't be a surprise for the Inter vs Atletico Madrid match.
