Form: Atletico continue to lead the way in La Liga with just six games remaining as despite being without top scorer Diego Costa and captain Gabi they did enough to squeeze out a 1-0 win over Villarreal on Saturday to secure a sixth straight league win.

Barcelona remain on their heels just one point behind as they too laboured to 3-1 win over Real Betis at the weekend.

However, there is nothing to separate the sides in four previous meetings this season as all four have ended in draws with both sides managing to score just twice.
