Form: Barcelona have bounced back from a run of three defeats in six league games to put themselves back in the fight to retain their La Liga title with four straight wins, most notably in beating Real Madrid 4-3 in El Clasico on March 23.

Lionel Messi's return to top form has played a huge role in his side's revival as the Argentine struck a hat-trick at the Bernabeu and now has nine goals in his last five games.

However, Barca remain a point behind Atletico in second with seven games of the La Liga season remaining as Diego Simeone's men remain on course for their first title since 1996 thanks to five consecutive league wins.

Diego Costa has led they way in a similar manner to the way Messi has for Barcelona as the Spanish international has struck 25 times in La Liga and has seven goals in just five Champions League appearances in his first season in the competition.
