Barcelona boss Frank Rijkaard called on his players to concentrate on their own form rather than becoming concerned with what Real Madrid are doing. "The main thing is that we keep on winning our games. There's no use always looking at what the other team is doing," Rijkaard was quoted as saying on the club's website. Primera Liga holders Real are in charge of the league table with 56 points, leading second-placed Barca by five points. However, Rijkaard is not willing to give up title pursuit. "Madrid are top because they have played better so far. But we're not giving in. We're prepared to fight in any competition," he said. Barcelona produced a superb form to beat Celtic 3-2 in the mid-week Champions League encounter. Rijkaard warned his players of complaceny ahead of their league game against Levante on Sunday. "People shouldn't take us for granted. But we have to come on against Levante in the right mindset."
