Osasuna upsets Atletico Madrid
Osasuna beat Atletico at its own game, both in its tough, physical approach and its set piece strategy to take a three-goal lead at the break after one of Atletico's worst first halves in three years under coach Diego Simeone.
Alvaro Cejudo opened the scoring from a corner kick in the sixth minute before fellow forwards Emiliano Armenteros and Roberto Torres added goals in the 21st and 42nd.
Atletico's loss came one day after Barcelona lost 3-1 at Real Sociedad, with both the former front-runners looking weary after their Champions League trips in midweek.
Atletico fullback Filipe Luis, who returned from injury, said that their win at AC Milan on Wednesday had nothing to do with this defeat.
''Osasuna played a great game,'' said Filipe Luis. ''You can't take anything away from them. They beat us in every facet of the game.''
Atletico and Barcelona have both dropped 10 points over the last seven rounds, allowing Madrid to turn a five-point deficit into a three-point lead despite playing without Ballon d'Or winner Cristiano Ronaldo during a three-game suspension. Madrid hadn't topped the standings since winning the title in 2011-12.
Simeone quickly needs to restore both his team's fitness and confidence before it hosts Madrid next weekend after its crosstown rivals travel to German side Schalke 04 on Wednesday.
