Barcelona happens to my favorite in this match and even the bookie seem to put the odds in favour of Barcelona, because it looks like everyone seem to believe Barcelona is.
Many times this season Barcelona has been my favorite team going into a match but on several occasions they don't leave up to the expectations and they have on those occasions went down first and then had to do the chasing game.
Although on some occasions Barcelona has really been impressive and fanatics especially when De Jong starts alongside pedri, I think a full Barcelona squad in form would definitely be a threat. Today's game they remain my favorite and I think they would win.
Don't worry, I think the levels of the two teams are very different although it is true that Barcelona also has some weaknesses. Barcelona appeared with their best squad, only Marc-André ter Stegen was listed as still injured. Barcelona fell behind Girona, but Barcelona responded quickly through Lewandowski's goal. This was Lewandowski's first goal in his last few games, so it will definitely help him regain his confidence.
Girona's advantage in this match is that they appeared without pressure because they knew Barcelona was a team that had more quality. Girona just wants to play the game with full confidence regardless of losing or winning, so I hope Barcelona can really use its advantage to win this game.
