Cristiano Ronaldo scored an exquisite back-heel to rescue a point for Real Madrid in their 1-1 draw against Athletic Bilbao on Wednesday. Madrid looked to be heading for defeat after Inaki Williams opened the scoring for the visitors after 14 minutes. But Ronaldo, restored to the starting line-up by head coach Zinedine Zidane, provided a deft flick from Luka Modric's 87th-minute drive to move Real to within three points of second-place Atletico Madrid having played one game more.
