Napoli couldn't secure a winning score against Blaugrana in the first leg and its pure motivation for Barcelona to fight back in the second leg. Barcelona will hosts Napoli in the second leg of round of 16, an important game that deserves the big winning from the exact club that clinched on winning form. Nobody gets a clear view except for clubs that have fought really hard to enter significant phase in the UEFA Champions League. Xavi Hernandez will ensure everything works smoothly as plan for his side because he already missed out on the La Liga title race but the UEFA Champions League will be intact for them this season.
Both Barcelona and Napoli are struggling, performance-wise. Their underperformance makes this match more uncertain. Barcelona has been inconsistent this season, especially against clubs they should have easily defeated. Inconsistency could be their downfall or incentive to prove everyone wrong. Barcelona's difficulties against smaller clubs in La Liga may be the motivator they need to beat Napoli.
Conversely, Napoli's key players arent performing as expected. This match is Barcelona's to lose due to their home advantage and need to recover from La Liga. Football is unpredictable, so Napoli may get the break they need. I believe a tough encounter could end in a tie. Barcelona must fix their inconsistencies to win and advance in the Champions League.
