Real Madrid edged the derby 3-2 against city rivals Atlético Madrid to remain in touch with LaLiga leaders Barcelona but the performance was far from convincing.
Having dragged themselves in front after a Vinícius Júnior penalty and Federico Valverde's sixth goal in five games overturned Ademola Lookman's first-half effort, they were unable to hold the lead for very long.
Substitute Nahuel Molina's brilliant, swerving strike from 25 yards restored parity and although Vinícius edged the hosts back in front, Valverde's purple patch ended when he was sent off with 13 minutes remaining for hacking at Alex Baena's ankle.
