Just like you, I'm quite optimistic about Barcelona's chances of qualifying for the last 16 because I really saw how they dominated the first leg. In Italy, Napoli could not do much after Barcelona surprised everyone with 3 goals in the first half, although Napoli managed to score 2 goals but Barcelona's good performance was able to overthrow them with a score of 2-4 in the second leg. Really it's a nice success at the moment from Barcelona.
Next I hope they can qualify for the next round against Galatasaray. I know now Barcelona will be favorites in the two leg vs Galatasaray but that doesn't guarantee they go through easily. Only a win and a good performance can see Barcelona through because every one of their opponents also wants to win the match to qualify.
Barcelona played like at Camp Nou when they beat Napoli at Stadio Diego Armando Maradona, Xavi Hernandez troops appeared little more dominating. Barcelona had more possession and created more chances than Napoli.
When beating Napoli with a score of 2-4, Barcelona performed beautifully with a thick tiki-taka feel, the scheme applied by Xavi Hernandez worked very well, they managed to qualify for the round of 16 after many doubted the quality of Barcelona this season.
Barcelona has put in an outstanding performance, they managed to answer doubts after poor start to the season.
Barcelona journey this season has been full of drama, they have been knocked out of the Champions League, Copa del Rey and struggled to catch Real Madrid points in the top flight of La-Liga. The Europa League is the only competition that Barcelona can still win this season, but Barcelona journey to the final is still long, in the round of 16 Xavi team was tested by the strength of Galatasaray, although Barcelona statistics are superior to Galatasaray, but in football anything can happen, such as Borussia Dortmund being eliminated by Rangers.
