Barcelona is still too tough for Osasuna because until now because looking at the situation that happened it seems that 3 points are definitely they get back with a 3-goal advantage now.
Barcelona's victory against Osasuna was predicted, from the composition of the squad and tactics, as well as H2H, there is no doubt that Barcelona can get a victory from this match. And when we look at the match statistics, they dominate in everything.
check here:

Even Osasuna did not have the opportunity to attack sharply and shoot shots on target, even though there were none. Not only that, Osasuna also made several mistakes, even 14 fouls, this is even twice as many as Barcelona players.
The statistics says it all Barcelona is not in the same level with osasuna even with the absence of some of their key players with this win Barcelona is now three points ahead of Madrid with 63 points am really impressed with the way Barcelona completely played controlled the game
Moving forward Barcelona should maintain this level of form because the league title is far from over because as far as I know any of the top three teams will win the laliga title so there is no room for laziness
