In the aftermath of the resignation of president Sandro Rosell, Barcelona will host Malaga on Sunday with staff and players trying to focus on retaining their share of the Spanish league lead.
Only one point separates Barcelona and co-leaders Atletico Madrid from third-place Real Madrid.
Barca play Malaga three days after president Sandro Rosell stunned the club and fans by announcing he was stepping down.
Rosell intends to fight criminal accusations he misappropriated funds by hiding the cost of the transfer to sign Brazil striker Neymar behind false contracts.
Vice president Josep Bartomeu has taken over and plans to see out the board's mandate until 2016.
"All our goals and objectives are the same," Bartomeu said.
"Our football team and teams in other sports will continue counting on our support and the resource needed to always aspire to the highest level of success."
With their fierce rivals immersed in an institutional crisis, Real Madrid host Granada on Saturday knowing that victory will provide the provisional lead.
Granada have proven to be one of the best away sides of the league this season, with more wins (4) than losses (3) on the road.
"The calendar gives us the opportunity to be leaders," Madrid coach Carlo Ancelotti said.
"After having been six points behind, that is important."
Cristiano Ronaldo will parade his recently won Ballon d'Or in front of his fans at Santiago Bernabeu before the match.
The Portugal forward will look to add to his league-leading tally of 21 goals through 20 rounds. He has scored 31 goals in 27 games in all competitions for Madrid.
Granada, however, stifled Ronaldo in their first meeting this season, when Karim Benzema's goal earned Madrid a 1-0 victory.
"Cristiano is a superb player," Granada coach Lucas Alcaraz said. "But since we can't stop Real Madrid from fielding him, what I try to do is to make my players do what we think is best for us within our style of play."
Atletico Madrid striker Diego Costa is having the best season of his career and he only trails Ronaldo by two with 19 league goals.
But the Brazilian-born forward, who has drawn serious interest from Spain coach Vicente del Bosque to take to the World Cup as a naturalised Spaniard, has yet to score in 2014.
Fortunately for Diego Costa, Atletico visit his former club, Rayo Vallecano, on Sunday in a capital derby.
Rayo are in second-to-last place having given up a league-worst 47 goals this season.
With the big three clubs far ahead of the pack, there are a number of teams left to aspire to a fourth-place finish and the prize of a spot in next season's Champions League.
Just past the season's midway mark, Athletic Bilbao sit fourth with Villarreal, Real Sociedad and Sevilla all within six points.
Bilbao face a tough trip to nearby Osasuna on Sunday. Villarreal travel to Valladolid on Saturday, when Sevilla host Levante.
