Every remaining La Liga fixture of the season for Barcelona is a must-win affair if Luis Enrique is to end his reign as manager with yet another league winners medal around his neck.
Real Madrid currently sit second to the Catalan giants in La Liga, level on points with the reigning champions, however, Los Blancos boast a game in hand, in which they will be crowned champions should they win all of their remaining games.
The chances of Real achieving that are quite likely you would imagine, but, nonetheless, Barcelona must continue to have belief in their pursuit of a third successive league title.

And things certainly went well for Enrique's men, who came away with what turned out to be a comfortable 4-1 home win, with the famed MSN trio bagging the goals.
Neymar opened the scoring after 20 minutes before Lionel Messi restored the lead on the stroke of half-time, following Cédric Bakambu's 32nd-minute equaliser, while Luis Suarez made it 3-1 in the second half and Messi rounding proceedings off with a successful spot kick.
However, if the title does, quite surprisingly, still manage to make its way to the Camp Nou at the end of the campaign, despite Real's advantage, Los Blancos fans might look back at one incident from this game.
Neymar's 10th league goal of the campaign was subject to much controversy and rattled Villarreal's defenders who were convinced the Brazil international's goal should have been ruled out for offside.
Neymar goal causes controversy
As can be seen in the video below, Neymar's head and shoulder partially appear to be offside when Messi puts his cross in and the forward follows up with a touch before tapping it past the 'keeper.
But the referee was not interested by the defenders' protestations and allowed the goal to stand.
In reality, it made little difference when the scoreline is considered. But the fact that the visitors later equalised suggests it could have changed the nature of the game had Villarreal been the side to take the lead.
And Real fans took to Twitter in their numbers to voice their displeasure with Neymar's opener.
It's safe to say Madrid's fan were not best impressed. But Cristiano Ronaldo's opener in the Champions League against Atletico Madrid in midweek also turned out to be offside.
Real closing in on title
Madrid also secured a comfortable victory with a 4-0 away win over Granada on Sunday evening, knowing there was no room for error with Barca having won earlier in the day.
Despite Real fans' anger at Neymar's opener, they will be satisfied that Zinedine Zidane's are closing in on their first La Liga title in five years.
Finally, it seems their league title woes are to come to an end.
