Barcelona can overtake Real Madrid if Real Madrid loses the 8 points they have collected so far in widening the gap with the clubs below them, but if Real Madrid does not lose points in the remaining 6 matches then Barcelona no longer has a chance to overtake, Real Madrid only has to play 4 matches again and that could lock up the Laliga title and will become champions this season and Barcelona looks like it will become second champion after Real Madrid if Barcelona doesn't lose points in the remaining games this season the point gap with Girona is not too far so it's better for Barcelona to focus more on defending second position rather than trying to catch Real Madrid who will continue to appear consistent.
If Real Madrid is eliminated in the Champions League, they will no longer have heavy pressure and will focus on La Liga, but perhaps this defeat could cause the players' mental balance to become unbalanced if they find it difficult to accept the reason that for 2 seasons Real Madrid was eliminated by Manchester City, but hopefully Real Madrid was able to turn things around even though they had to play away at the Etihad, with that the players' mentality will be safe and will try to perform well in Laliga and also the Champions League.
Xavi has been a good manager at the Spanish side, even though they've had some shaky situations, they've just found a way to cover up lapses and make necessary coverings to the loopholes. It's very much good that they were able to put in good effort regardless of what to they lacked to good team building. Nonetheless, Xavi would have still done better than he's already done.
So far this season, Real Madrid have been very much active and set towards the La Liga trophy goal. They've in many weeks played games and ensured good results that's gotten and kept them in the top spot of the league table. Even though a couple of times, their performances have been reducing in range, they've still being able to manage a win before the end of the game.
Well, they still have the champions confidence and determination in them too, adding that their manager is very much experimental in his approach to their games. They're a good team and they sure do know how to fix up their errors. Well it's very much essential that they correct errors faster and avoid incidents that are drastic and costly to occur as the times left won't entertain mistakes because it'll only be irreparable.
