Barcelona can reduce Real Madrid's lead at the top of La Liga to just one point when they take on 10th-placed Getafe on Tuesday evening.
With just seven games remaining in the championship, the Catalans can ill afford any more slip ups as they pursue Jose Mourinho's men. And that looks unlikely with Barca winning their last five league outings and scoring 13 times in the process.
Barcelona came from behind to beat Real Zaragoza 4-1 on Saturday and were delighted to see Real drop points for the third time in five games when they drew 0-0 with Valencia on Sunday night.
The capital side's lead over their bitter rivals has been reduced from 10 to four points in the space of just a few short weeks.
With the Madrid derby due to be played on Wednesday night at the Vicente Calderon Stadium, Pep Guardiola's troops can really pile the pressure on the Madrid with a win at Camp Nou.
In Tuesday's other matches, Espanyol travel to Osasuna and Real Sociedad take on Betis. All three matches kick off at 1900 GMT and will be streamed live online at Unibet.
