Ahead of the encounter, Goal brings you everything you need to know about the UEFA Super Cup 2018, including when and where it takes place, how to watch it live and more.
What is the UEFA Super Cup?
The UEFA Super Cup is an annual football match contested by the champions of the continent's two main club competitions - the Champions League and the Europa League.
Usually played in August, the game serves as a sort of curtain-raiser for the upcoming European club season, with the group stages of the aforementioned tournaments primed to kick off in September.
Dutch sports journalist Anton Witkamp came up with the concept in 1971 and it has gone through a number of changes since its inception.
Initially, the competition incorporated two matches - home and away legs - but it has been a single-game decider since 1998, with games taking place at neutral venues.
When is the UEFA Super Cup 2018?

The 2018 edition of the UEFA Super Cup between Real Madrid and Atletico Madrid is scheduled to be played on Wednesday August 15.
The game will kick off at 10pm local time, which means 8pm BST in the United Kingdom and 3pm ET in the United States.
It takes place four days before Real Madrid get their Liga season under way against Getafe and five days ahead of Atletico's opener against Valencia.
Where is the UEFA Super Cup 2018 being held?
Estonia will host the 2018 edition of the UEFA Super Cup, marking the first ever time a European club final has been held in the country.
Lillekula Stadium, or A. Le Coq Arena, in the capital city of Tallinn will be the venue for the game.
The ground, which was first opened in 2001 and has a capacity of roughly 15,000, is home to the Estonia national team and Meistriliiga side Flora Tallinn.
From 1998 to 2012 the UEFA Super Cup used to be held at Monaco's Stade Louis II, but it is now rotated around the continent.

Who won the last UEFA Super Cup?
Real Madrid won the last edition of the UEFA Super Cup in 2017 by defeating Jose Mourinho's Manchester United 2-1 at the Philip II Arena in Skopje, Macedonia.
Casemiro and Isco got the goals for Los Blancos on that occasion and, despite Romelu Lukaku narrowing the deficit, they held on to secure their fourth Super Cup triumph.
The 2017 Super Cup win was Madrid's second in as many years, following their 2016 victory over fellow Spaniards Sevilla.
Barcelona and AC Milan are the most successful clubs in the history of the competition, with each side boasting five titles each, and Real Madrid can join them with a win over city rivals Atletico in Tallinn.
