Barcelona conceded twice in 68 seconds and Real Madrid were three down at half-time as La Liga’s two title favourites were each stunned by surprise defeats on Wednesday night.
Barca’s 2-1 loss to relegation fighters Leganes was the greater shock but Madrid’s beating was more emphatic, blown away 3-0 by Sevilla after a torrid 39 minutes at the Ramon Sanchez Pizjuan.
For both, it was their first defeat of the season and for both, defensive fragility was the key factor, which will be a major concern with the second round of Champions League games to come next week.
By the end, Atletico Madrid, who had cruised to victory over Huesca on Tuesday and play Real on Saturday, were the biggest winners. After a stuttering start, Diego Simeone’s side will jump above Real with a win at the Santiago Bernabeu.
Sevilla can be a formidable opponent on their own patch but few expected Leganes to inflict what was only Barcelona’s second league defeat in 17 months.
“We are in a very difficult moment that was unexpected,” Barca coach Ernesto Valverde said.
