With the points that Barcelona has, it feels like this will be very easy to control. The opportunity for Madrid to catch up is also getting further away, so Xavi and his squad will play a little and control the situation in order to keep his players from getting injured.
Barcelona's fate this season is not much different from what was experienced by Arsenal, both of them tried to get up with the formation of young players, and both Xavi and Arteta managed to fulfill their desire in securing a trophy. Elche will not threaten Barcelona's defense too much with the track record of meeting the two on paper even before the match Barcelona had won a landslide victory.
It's not surprising that Barcelona are at the forefront of becoming Laliga champions after Xavi has managed to do a good job in recent times which has allowed Barcelona to widen the points gap with Real Madrid. Elche will be the next opponent for Barcelona in the upcoming match which incidentally will be a little easier for Barcelona to take advantage of their opponent's weaknesses in the upcoming match.
From the start of the Barcelona season which was hit by a financial crisis which made Barcelona have to have a few obstacles in the transfer window but this has become a reality if all the efforts made have succeeded in making Barcelona strong again, If barcelona becomes the Laliga title winning team this season then I'm sure from a financial point of view they will be fresh again next season.
