Barcelona visit Rayo Vallecano this weekend looking to go clear at the top of La Liga.

The Catalan giants thrashed Saturday's opponents 7-0 when the two teams last met, and go into the game unbeaten in the league during the current campaign.

Paco Jemez's side are in erratic form, lying in mid-table on a run of just one win in six.

Alex Song could continue deputising at the back for the visitors with Carles Puyol and Gerard Pique likely to be passed unfit.

Piti and Alejandro Dominguez are expected to lead the attack for Rayo Vallecano.

Recent form:

Rayo Vallecano: LLLWL

Barcelona: WWDWW

Possible lineups:

Rayo Vallecano: Andrade; Tito, Casado, Labaka, Galvez; Carlos, Fuego, Abu, Baptistao; Piti, Dominguez

Barcelona: Valdes; Alves, Song, Mascherano, Alba; Fabregas, Xavi, Iniesta, Adriano; Messi, Pedro
