The draw against Girona won't change anything for Barcelona to win the title of Laliga for this season because their competitor Real Madrid lost the game against Villarreal and this increased the gap between these two teams because this week Barcelona lost two points Real Madrid lost three points but generally Barcelona is not in a good situation after the lost the El Clasico in Copa Del Rey against Real Madrid.
Now Barcelona only needs to take care of themselves not to lose the remaining matches in this season so they can confirm the championship early in La Liga this season because apart from not changing anything with the draw obtained by Barcelona, Barcelona's advantage also continues because remember Real Madrid were unable to get any points against Villarreal. So Barcelona now only needs to focus on getting points in every game even if it's only with one number.
Already Barcelona has enough points to guide them against any contender, not even Real Madrid will have access to FCB in that position in as much as La liga is consent. Barca may lose some matches, But not to an extent of losing their leading points. Barcelona priority now is securing that title and nothing seems to stop them cuz the work input required is less compared to some weeks ago this is because the remaining matches left isn't Tough.
If Barcelona is defeated in 5 matches, Madrid will be able to move to the top of the table. But Madrid must win all the matches. Firstly, it is unlikely that Madrid will win all the matches. And secondly, I don't see any chance of Barcelona losing 5 out of 10 matches. Barcelona might lose 2/1, or draw, but they won't lose the top spot in the table. Xavi is quite an experienced coach. His aim is to make the team more stable. And to prepare the team for the upcoming Champions League. Hopefully, Xavi will succeed and the Barcelona team will become stronger.
In theory it could still go wrong, yes, but how much good is that? I think the chances are so small that it is probably impossible to express it in percentages. And bookmakers will also not offer odds to bet on barcelona. Or the 1st team of Barcelona should get full covid, lung covid. And then they are off for a few months. The question is rather when they are officially champions and how seriously Real Madrid will take the last games. Because Real has done good business in the CL, so they will fully focus on that. National title doesn't have much value either. Every year it is a duel between Barcelona and Madrid.
