I only compare the performance of each club in the group stage and in my opinion the club from the Premier League is more convincing while between Barcelona and Napoli I think Barcelona can still be favored if we see based on the last performance of each club. This is just my personal opinion you can agree or ignore it but of course I took a comparison of the last performance of the two teams and this prediction is not permanent because I have said the strength of each club can change if they are actively bringing new players in the transfer window. Another thing that makes me sure Barcelona can beat Napoli is based on schedule, the first leg will be played at Napoli home then the 2nd leg at the Barcelona home well usually the 2nd leg as a determinant and Barcelona as a home team has an advantage.
