Real Madrid hit the woodwork three times but could only draw 0-0 at home to Athletic Bilbao in a frustrating final game of 2019 which meant they slipped two points behind La Liga leaders Barcelona.
Real's top scorer Karim Benzema had a shot cleared off the line in a lively first half while Toni Kroos came within inches of scoring when he waltzed through the defence and hammered a shot which Athletic keeper Unai Simon deflected on to the bar.
Substitute Nacho Fernandez rattled the bar in the second half while Serbian forward Luka Jovic left Simon flat-footed with a late header but watched as the ball bounced off the post and Sergio Ramos scuffed the rebound back at the goalkeeper.
Athletic, who beat champions Barca earlier this season, gave an astute performance in defence and also gave their hosts a few scares, with Kenan Kodro having a goal ruled out for offside and Inaki Williams forcing Thibaut Courtois to make a diving save.
It was Real's third draw in a row after 1-1 and 0-0 stalemates away to Valencia and Barca respectively, games in which they also played well but lacked composure in front of goal.
