I am sure it will happen, although Real Madrid still has the opportunity to defend the title but now we can see how the strength and consistency shown by Barcelona makes their percentage to win the La Liga title this season quite large especially since Real Madrid throughout this season has been very inconsistent so that it can be utilized by Barcelona.
If we talk about eligibility, of course Barcelona deserves to win the La Liga title this season, they have shown extraordinary performance which is much better than last season.
In terms of eligibility, it is quite obvious that Barcelona deserves to be the champion in La Liga this season, but we also need to see that Real Madrid's chances of getting it have not disappeared at this time. Because we also don't know what will happen in the rest of this season to Barcelona so Real Madrid only needs to beat Barcelona when they meet again in a match in La Liga this season. Although Real Madrid still has to hope that Barcelona does not get full points when competing with other opponents.
If you look at the standings, both Barcelona and Real Madrid have the same number of points, namely 60 points. However, Barcelona technically has 63 points. Because, they have not played one more match and we know who will win the match, it must be Barcelona. Because the match will be played in front of their own supporters and the opponent they face is Osasuna which on paper Barcelona is superior to everything.
In addition, Barcelona's confidence and mentality have increased after defeating Atletico Madrid last week in a very epic manner. So Barcelona's chances are much greater than Real Madrid's to win the La Liga trophy, although there is no guarantee, but statistically Barcelona currently has that chance. So their chances of winning La Liga are big but not in the Champions League.
