Real Madrid's La Liga title chances took another heavy blow on Saturday night as they were held to a goalless draw by Osasuna.
Los Merengues struggled to create chances against their bottom-of-the-table opponents and needed half an hour to produce their first real opportunity. Gonzalo Higuain made it all the way to the byline but his cross was cleared by Alejandro Arribas.
Madrid's troubles continued and they could only manage an unconventional headed effort at goal from Jose Callejon who found the roof of the net.
Osasuna looked comfortable defending what Real Madrid threw at them and threatened to take the lead when Alvaro Cejudo blasted a half-volley inches over the bar.
The visitors had a great chance to break the deadlock on the stroke of half-time when Andres Fernandez was caught out of position by Callejon who set it up for Fabio Coentrao, but he sent his shot wide of the target.
Shortly after the break the hosts came close as Kike Sola cut in from the left and forced a save from Iker Casillas, who had a quiet game up to that point.
Kaka and Karim Benzema were introduced just before the 60-minute mark, but failed to make an impact. The Brazilian picked up a yellow card almost immediately and was then sent off for a second offense in the 76th minute as Real went on to draw the game.
