Cristiano Ronaldo returned for Real Madrid, who were looking for a home win after two consecutive draws in the Liga Santander in front of their fans on Wednesday, reports Xinhua news agency.
However, a combination of poor finishing, bad luck and good saves from Betis keeper Antonio Adan kept them at bay as they laid siege to the Betis goal in the second half and Zinedine Zidane’s side were caught by a sucker punch by the Paraguayan, who moments earlier had seen a goal correctly ruled out for being offside.
The defeat leaves Madrid seven points behind Barcelona at the top of the Liga Santander.
