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.
Of course, Barcelona has a loose schedule after being eliminated from the Europa league so it's easier to control the game in La Liga. Barcelona players have sufficient rest hours because they only focus on two competitions, La Liga and the Copa Del Rey.
Barcelona situation is very supportive to win the La Liga trophy, a 12 point advantage over its main competitor makes Barcelona want to be at the finish line soon. Barcelona only needs 25 more points to lock in the title, this number could still be reduced if Real Madrid loses points in several games. If Barcelona are consistent with their performances, Real Madrid must give up the title for Barcelona and they must be prepared to congratulate their rivals.
