Madrid: FC Barcelona face another potentially difficult away game on Sunday as they seek to maintain their five-point lead at the top of the La Liga football championship. The lead could have been reduced to two or three points by the time Barcelona kick off in Villarreal if Valencia and Atletico Madrid win their respective matches, which will have finished before the game starts in the Estadio de la Ceramica. Villarreal have not beaten Barcelona at home in 10 years, but their ground has always been a difficult place for the Catalan powerhouse. The home side has lost three consecutive defeats coming into the match. They lost at home ain’t Sevilla and away against Leganes, while a side made up mainly of B-teamers lost in the Europa League on Thursday.
