Hakim Ziyech opened the scoring for Chelsea before going off injured
Extra-time was required to decide the first European trophy of the season after Villarreal pegged back Chelsea as the UEFA Super Cup final finished 1-1 after 90 minutes on Wednesday.
A dominant start by the European champions was rewarded in Belfast as Hakim Ziyech fired Chelsea into a 27th minute lead, but Gerard Moreno's equaliser was no more than Villarreal's improved second-half display deserved.
