Porto had made it to the Super Cup after beating Celtic in the 2003 UEFA Cup Final. Milan won the match 1–0.

The Stade Louis II in Monaco has been the venue for the UEFA Super Cup every year since 1998. Built in 1985, the stadium is also the home of AS Monaco, who play in the French league system.

The UEFA Super Cup (also called the European Super Cup) is an annual football game between the reigning champions of the two club competitions organised by the European football governing body UEFA: the UEFA Champions League and the UEFA Europa League. It takes place at the start of the domestic season, in August, normally on a Friday.

From 1972 to 1999, the UEFA Super Cup was contested between the winners of the European Cup/UEFA Champions League and the winners of the European Cup Winners' Cup/UEFA Cup Winners' Cup. After the discontinuation of the UEFA Cup Winners' Cup, it has been contested by the winners of the UEFA Champions League and the winners of the UEFA Cup, which was renamed the UEFA Europa League in 2009.

The current champions are Spanish club FC Barcelona after they beat F.C. Porto 2–0 in the 2011 UEFA Super Cup. The most successful team in the competition is Italian side A.C. Milan, who have won the trophy five times. The next edition will be held between Chelsea F.C., winners of the Champions League and Atletico Madrid, winners of the Europa League.

Zinedine Zidane (French pronunciation: [zinedin zidan]) (born 23 June 1972) is a retired French footballer. Zidane was the leading figure of a generation of French players that won the 1998 World Cup and 2000 European Championship. After a brief international retirement, he returned to the national team in 2005 and captained France to the 2006 World Cup Final where he won the Golden Ball as the tournament's most outstanding player.

In club level Zidane won the La Liga and the UEFA Champions League with Real Madrid, two Serie A league championships with Juventus and an Intercontinental Cup and a UEFA Super Cup each with both aforementioned sides. He is one of only four players to have been FIFA World Player of the Year three or more times (Brazilian forward Marta is a five time winner (female award), while Brazilian striker Ronaldo (male award) and German striker Birgit Prinz (female award) have won three each). He also won the Ballon d'Or in 1998. He retired from professional football after the 2006 World Cup.

Cristiano Ronaldo dos Santos Aveiro,OIH, (born 5 February 1985), commonly known as Cristiano Ronaldo, is a Portuguese footballer who plays as a winger or striker for Spanish La Liga club Real Madrid and is the captain of the Portuguese national team. Ronaldo became the most expensive footballer in history after moving from Manchester United to Real Madrid in a transfer worth £80 million (€93.9 million/$131.6 million). In addition, his contract with Real Madrid, in which he is paid €12 million per year, makes him one of the highest-paid footballers in the world, and his buyout clause is valued at €1 billion as per his contract.

Ronaldo began his career as a youth player for Andorinha, where he played for two years, before moving to C.D. Nacional. In 1997, he made a move to Portuguese giants Sporting Clube de Portugal. Ronaldo's precocious talent caught the attention of Manchester United manager Alex Ferguson, who signed him for £12.24 million (€15 million) in 2003. The following season, Ronaldo won his first club honour, the FA Cup. He also played at Euro 2004 with Portugal and scored his first international goal in the opening game of the tournament against Greece, in addition to helping Portugal reach the final. He was featured in the UEFA Euro All-Star Team of this competition.

Lionel Andrés Messi (Spanish pronunciation: [ljoˈnel anˈdɾes ˈmesi], born 24 June 1987) is an Argentine footballer who plays in La Liga for FC Barcelona and is the captain of the Argentina national team, mainly as a forward.

By the age of 21, Messi had received Ballon d'Or and FIFA World Player of the Year nominations. The following year in 2009 he won both the Ballon d'Or and FIFA World Player of the Year, and won the inaugural FIFA Ballon d'Or in 2010 and 2011. He also won the 2010–11 UEFA Best Player in Europe Award. Messi is the fourth football player to win three Ballons d'Or, after Johan Cruyff, Michel Platini and Marco van Basten and the second player to win three consecutive Ballons d'Or, after Michel Platini. His playing style and small stature have drawn comparisons to Diego Maradona, who himself declared Messi as his "successor".

Messi has won five La Liga titles and three Champions League titles. In 2012, Messi made UEFA Champions League history by becoming the first player to score five goals in one match, in a 7–1 win against Bayer Leverkusen. With two goals in the next round against A.C. Milan, he matched José Altafini's record of 14 goals in a single UEFA Champions League/European Cup season. He also became the first player to top-score in four successive European Champion Clubs' Cup campaigns. He set the world record for most goals scored in a season during the 2011–12 season, with 73 goals.
