Four clubs with UEFA Champions League aspirations top the bill for this week's La Liga fixtures. The quartet of Atletico Madrid, Sevilla, Valencia and Villarreal will all be looking to gain an advantage at the formative stages of the season. Wins for Sevilla and Valencia would put them on six points from six, leaving Atletico and Villarreal on one point between them. Even at this early stage, it's vital to keep in touch at the top. Villarreal, who host Sevilla, will be keen to prove their 5-0 defeat to Barcelona reflected more on the La Liga champions than themselves; Sevilla, meanwhile, will look to continue momentum from their 2-1 win over Malaga - another team in Champions League contention. Alvaro Negredo scored both goals in Sevilla's win and was again in fine form midweek with another brace, this time on the international stage in Spain colours. He will need to be in fine form if Sevilla are to make it two wins out of two, while Villarreal know avoiding defeat is imperative for both their points total and general morale.
