The title could even be decided before hand should Real Madrid and Atletico Madrid drop points prior to Barca's Sunday night showdown.

Los Blancos host Getafe in a Madrid derby, while Atleti appear to have a more straightforward task against bottom club Elche.

But a defeat for Diego Simeone's side coupled with dropped points for Carlo Ancelotti's men would see the Blaugrana take to the field as LaLiga champions on Sunday night.

The visitors go into this match knowing that a win over their relegation-threatened rivals will see them crowned LaLiga champions for a 27th time.

Encouragingly for the Blaugrana, this derby has been exceptionally one-sided of late — Espanyol have not won any of the last 25 clashes between the two (seven draws, 18 defeats).

In fact, Barca's 101 top-flight victories over their neighbours are the second-most wins any club has recorded over another in the competition's history.

If Robert Lewandowski can find the net in this crucial clash, he will become the joint-third fastest player to reach 20 LaLiga goals in the 21st century (level with Julio Baptista and behind Radamel Falcao and Cristiano Ronaldo).

At the other end of the table, Valencia's fight for survival continues with an important away clash against Celta Vigo.

Real Marid will be keen to avoid a second successive LaLiga slip-up after losing 2-0 at Real Sociedad last time out — especially in a regional derby against Getafe.

But Los Blancos should be boosted by their history in this fixture. They have won 71.4% (25/35) of their top-flight games against Saturday's visitors, with no team having a better win percentage against them in the competition.

Furthermore, Getafe have lost each of their last 13 league fixtures at the Bernabeu — their worst losing run away from home against a single opponent.

Azulones boss Jose Bordalas may struggle to inspire his troops to defy the odds given he has not managed more games against any team without winning (two draws, eight defeats) than this weekend's opponents.

Real will hope to use victory in this encounter as a springboard ahead of their crucial Champions League semi-final second-leg meeting.
