Real Madrid slumped to a 2-1 defeat at Real Betis after their former player Isco converted a second-half penalty on Saturday, denying the visitors the chance to top LaLiga.
The loss leaves Real Madrid level points with leaders Barcelona, who host Real Sociedad on Sunday.
Madrid dominated the early proceedings and took the lead after 10 minutes when Brahim Diaz tapped in Ferland Mendy’s pass from the left after a great through ball from Kylian Mbappe.
Betis overcame the sluggish start, though, and equalised in the 34th through Johnny Cardoso’s close range header off a corner from Isco.
Madrid goalkeeper Thibaut Courtois pulled off a crucial save to deny Cardoso a second goal shortly before halftime.
The defender could not prevent Isco from scoring a clinical spot kick to hand Betis the lead nine minutes after the break following Antonio Rudiger’s foul on Jesus Rodriguez.
Carlo Ancelotti sought to spark some life into his attack with the introduction of Arda Guler and Endrick, but Betis’ backline held firm while goalkeeper Adrian blocked a late attempt from Vinicius Jr.
