Kepa Arrizabalaga was the hero as Chelsea secured their first Super Cup triumph since 1998, running out 6-5 winners in a penalty shoot-out against Villarreal following a 1-1 draw in Belfast.

Hakim Ziyech opened the scoring after good work down the left flank from Kai Havertz before the former Ajax man's shoulder injury marred an entertaining first half.

Alberto Moreno and Gerard Moreno both hit the woodwork either side of half-time, though the latter restored parity with a fine finish to send the final to extra time.

Kepa, who was brought on in the closing minutes solely for penalties, denied both Aissa Mandi and Raul Albiol to make sure Chelsea came out on top.

The Champions League holders had started proceedings impressively too, Timo Werner forcing the first save as Sergio Asenjo had to react quickly to parry away a close-range effort from Havertz's inswinging corner.

Asenjo, though, was no match for Ziyech's sweeping finish after Havertz found space on the left and drilled towards his team-mate near the penalty spot.

Ziyech's injury, suffered while defending a set-piece situation, offered Thomas Tuchel a reason to be concerned, with Alberto Moreno then smashing an effort onto the crossbar.

Gerard Moreno was also denied in similar circumstances after the break, capitalising on Edouard Mendy's wayward clearance before seeing his low strike smack the post.

However, the Villarreal forward quickly made amends, exchanging a one-two with Boulaye Dia before lifting over Mendy for his 23rd goal of 2021, ranking him fifth across Europe's top-five leagues.

Both Christian Pulisic and Mason Mount could not find extra-time winners and, with a shoot-out in sight, Tuchel sent on Kepa.

Opposite number Asenjo drew first blood with a stop against Havertz, but that advantage faded away when Kepa saved for the first time.

With no further misses between the other eight takers, sudden death kicks were necessary. After Antonio Rudiger rolled in his attempt, Kepa guessed the right way to deny Villarreal captain Albiol.

Manchester United will face European debutants Granada in the quarter-finals of the Europa League and cannot now meet Arsenal until the final.

The draw for the last eight on Friday kept the two remaining Premier League giants apart.

United claimed a 1-0 win at Milan on Thursday to advance 2-1 on aggregate and their reward is an apparently kind draw against LaLiga's Granada, winners over Molde.

If United advance, they could have a replay of the 2016-17 final in which they defeated Ajax, who take on Roma for the right to play the Red Devils or Granada.

Ajax were too strong for Young Boys, while Roma dumped out Shakhtar Donetsk.

Arsenal, who knocked out Olympiacos despite losing at home, will be wary of their quarter-final opponents Slavia Prague.

Slavia have already eliminated Leicester City and Rangers, and have now been paired with the 2018-19 finalists, visiting Emirates Stadium before hosting the reverse fixture.

Arsenal's half of the draw is completed by Dinamo Zagreb and Villarreal.

Dinamo defeated Tottenham in a stunning second-leg comeback on Thursday and could get the chance to complete a north London double if they meet the Gunners.

A meeting between Arsenal and Villarreal would also have significance, with the Spanish outfit coached by Unai Emery, Mikel Arteta's predecessor and a three-time Europa League winner with Sevilla.

Emery's men swept aside Dynamo Kiev in the last 16.

Quarter-final draw:

Granada v Manchester United
Arsenal v Slavia Prague
Ajax v Roma
Dinamo Zagreb v Villarreal

Semi-final draw:

Winner of QF 1 v Winner of QF 3
