MADRID, Nov. 21 (Xinhua) -- Fourth-placed Valencia looks to keep the pressure on in the three teams above them in the BBVA Primera Liga table when Unai Emery's side plays away to Osasuna on Sunday night.

    With Sevilla, Real Madrid and Barcelona all playing on Saturday, Valencia's players know that should Sevilla lose in Tenerife and Real Madrid slip up at home to Racing Santander, they can move above Sevilla to just one point behind Real Madrid.

    Osasuna, however, will be tough rivals, despite an outbreak of Swine Flu that has left four players struggling to be fully fit.

    Winger Juanfran says he will play if needed, but the club will probably prefer to maintain him separate from his companions to avoid risk of infection.

    Valencia's main problem could be tiredness after Carlos Marchena, David Silva, David Villa, Juan Mata and Pablo Hernandez only returned to the club on Thursday after international duty with Spain.

    Elsewhere there is plenty of tension. Bottom of the table Malaga recovers players such as Juantio, Apono, Rosario and Luque from injury for the visit of Zaragoza.

    However, with his side bottom of the table with no win since the first day of the season, Malaga coach Juan Muniz needs a win or else he could lose his job.

    Villarreal will look to striker Nilmar, who scored two goals in two games for Brazil last week, to spearhead its charge against Valladolid.

    Villarreal lost its last game 3-2 away to Sevilla, but Ernesto Valverde's team is showing signs of recovery after a poor start to the season.

    Second from bottom Xerez receives the visit of seventh placed Sporting Gijon and the crowd should be in good spirits after a week of demonstrations to help the club out of its current financial crisis.

    Sixth placed Mallorca welcomes top scorer Aritz Aduriz back from injury for the home game against Almeria.

    Almeria coach Hugo Sanchez was booed by his own fans as his side was knocked out of the Kings cup 10 days ago, but with his team in a comfortable 11th place, his job looks to be safe for the moment.

    Finally Espanyol receives Getafe in a mid-table battle.
