Barcelona travel to Balaídos Vigo to take on Celta Vigo as they try to cement their spot at the top of the La Liga.
After a disappointing trophyless last season, Barcelona are doing very well in all the competitions so far as they are in the finals of the Copa Del Rey, the quarter-finals of Champions League and top of the La Liga.
They have been especially very impressive in La Liga, having won 10 of the 12 fixtures since the turn of the year.
This run of good form has seen Barcelona displace rivals Real Madrid from top of the La Liga and open up a four-point cushion over them.
However, Barcelona cannot afford to put down their guard in this final stretch of the season and manager Luis Enrique insists that he is taking nothing for granted.
"I think it's highly unlikely that any of the four teams still in contention for the title will win all of their remaining games," he told reporters, according to Goal. "Of course, I might be wrong, and if I am then I hope I'm wrong about Barca."
Although Barcelona are expected to record an easy win at Celta Vigo, who unexpectedly defeated them at Camp Nou earlier this season, considering their current form, Enrique insists that there are no easy games at this stage of the season.
"All games are important," Luis Enrique added. "From now on, there won't be any easy opponents. Celta will be dangerous because they need points and the championship is getting near to the end."
Meanwhile, Celta Vigo will also be hoping to get a positive result against Barcelona despite them being clear underdogs in this fixture.
Celta are going through a lean patch of late, recording only one win in their last four La Liga fixtures, but manager Eduardo Berizzo is "hopeful" that his side will be able to repeat their earlier performance against the Catalans on Sunday.
"That's what we are hoping to do and what motivates us going into the game. We all know we are up against a great side, who are the league leaders, so all this makes us even more motivated to beat them", said the Argentine, according to Maraca.
"We will try to keep possession of the ball because that's what you need to do against teams like Barça to relieve the pressure. We have to put on a brave performance".
Although teams generally defend against Barcelona, Berizzo insists that Celta will be playing their natural attacking game against the Catalans on Sunday.
"We always try to play on the attack and tomorrow will be no different. We will try to keep possession of the ball because that's what you need to do against teams like Barça to relieve the pressure. We have to put on a brave performance".
Celta Vigo: Alvarez, Mallo, Cabral, Castro, Fontas, Krohn-Dehli, Fernandez, Orellana, Mina, Nolito, Charles
Barcelona: Bravo, Alves, Pique, Mathieu, Alba, Mascherano, Iniesta, Rakitic, Neymar, Suarez, Messi
