Chelsea will kick off their 2021/22 campaign by facing Villarreal in the UEFA Super Cup just three days before the Premier League opener.
The Blues host London rival Crystal Palace in the opening game of the new season on Saturday August 14 at 3 p.m. ET.
But before that, they will make the trip to Belfast for the UEFA Super Cup.
Chelsea beat Manchester City in the Champions League final last season and will now face Europa League-winning Villarreal in the Super Cup.
West Londoners have featured in the flagship game four times, winning it just once in 1998.

Villarreal, who beat Manchester United to Europa League glory in May, will make his Super Cup debut.
Chelsea will be relieved that the game takes place at Windsor Park in Belfast, meaning they won’t have to travel long before their first Premier League game.
