You are right. With the way Atlético Madrid's performance is going recently, they are declining in performance, which already affects them in the title race. As you said, it now remains Barcelona and Real Madrid to compete for the title race, although I’m still expecting Barcelona to be at the top for the remaining period of the season. I know Barcelona will dominate their matches.
Xabi can do everything possible to see that they succeed this season, and I’m sure Barcelona will do it. They won’t give up at this point and won’t make any wrong move that will spoil their chances of getting the league title.
Everything can happen in football, but as you can see, Real Madrid and Barcelona are close, which allows them to share points. However, Barcelona's mind won't rest because their minds have already split in a number of ways, and if care is not exercised, they will soon push them out of the top spot; Any minor error now, they will lose points.
Even though Atletico is making every effort to overtake Real Madrid and Barcelona at the top of the standings, their current performance is preventing them from doing so. Nevertheless, since they still have games left to play and are only four points ahead of those two teams, I hope they can share the lead.
