As Xavi said, 12 points ahead of rivals Madrid. doesn't make them satisfied, approaching the end of the season Xavi and his team must be more consistent to stay on the winning path. after all, La Liga still leaves 12 matches until this season ends. meaning, Xavi must maintain the consistency of his team in more crucial phases. at least, if Barcelona confirms the title, they have to win 9 of the remaining 12 matches. not an easy journey, because all the other teams will also focus more on increasing their rankings.
Meanwhile, it doesn't mean that Madrid doesn't have the opportunity to reduce the point difference from Barcelona. Don Carlo could have focused his team, to focus on winning the remaining matches. plus, hope that Barcelona will slip 4 or 5 in the next match. With that, Madrid has the opportunity to overtake Barcelona. However, this is just my scenario and doesn't mean anything. well, let's just enjoy it when these two teams play game after game until the end of the season.
Xavi has to say this, so that the players don't relax until they reach the point where Real have no even theoretical chances to catch up with Barcelona. But even 12 points is a very big advantage, which is almost impossible to reduce against such a Barcelona. They have yet to play the second leg of the Copa del Rey, Ancelotti will try to at least win this match, but in La Liga, Real have very little chance.
You are right. Real Madrid's chances of winning the La Liga title are slim. Real Madrid will play 12 more matches this season. And they are 12 points behind Barcelona. Barcelona lost 4 out of 12 matches and Madrid winning all matches is unlikely. And so Ancelotti should now try to win the Copa del Rey title. But the chances of that are also low for Real Madrid. Because Barcelona won the first leg. Barcelona's defense is very strong. I think if they play defensively they will be able to draw the second leg.
