UEFA awarded the right to host the final to the Stade de France in Saint-Denis after considering its merits in terms of capacity, stadium infrastructure and dossiers including city and airport agreements and promotional plans. UEFA also conducted a variety of site visits. The Stade de France previously staged the 2000 UEFA Champions League Final between Real Madrid and Valencia, which Madrid won 3–0 and was the first time two clubs from the same country had faced each other in the final. Saint-Denis was chosen to host the final in recognition of the 50th anniversary of the first European Cup final in 1956, held in nearby Paris at the Parc des Princes, now home of Paris Saint-Germain. The Parc des Princes also hosted the 1975 and 1981 European Cup finals, the 1978 and 1995 UEFA Cup Winners' Cup finals, and the 1998 UEFA Cup Final.
Barcelona were to show the match live from their Mini Estadi on a 70-metre (230 ft) television screen for an estimated audience of 15,276. Before the final an estimated 1.2 million people converged on to the streets of Barcelona, as the team toured the city on two open-top double-decker buses to celebrate winning La Liga. Arsenal went into the match with the record for the longest time without a conceding a goal. They had gone 919 minutes without conceding since conceding against AFC Ajax in the group stages. Arsenal were featuring in their first European final six years to the day since their last final. They faced Galatasaray in the 2000 UEFA Cup Final; the match had finished goalless after 90 minutes and extra time. Arsenal lost the subsequent penalty shootout 4–1. Of the players who featured in that final, only Thierry Henry and Dennis Bergkamp remained at the club, whilst Sylvinho, who had featured for Arsenal in the final, was now a Barcelona player.
The 2006 final was the first time that Arsenal had reached the showpiece match; in doing so they became the first club from London to feature in the final. Barcelona were appearing in the final for the fifth time; their last appearance had been in a 4–0 loss to Milan in 1994. Two more losses preceded the 1994 final (1961 and 1986), and their only success in the competition came in 1992 when they beat Sampdoria. Barcelona went into the final as domestic league champions, having won La Liga a fortnight earlier. They were regarded as being the best side on the continent because they possessed players such as Ronaldinho and Samuel Eto'o. Barcelona player Deco dismissed the notion of Barcelona being favourites, insisting they would not be complacent: "Milan were winning 3–0 last year against Liverpool and ended up losing in the end. We need to be serious, calm and fully concentrated so that we don't make any errors".
Neither side had been beaten en route to the final, with Arsenal only conceding two goals in their 12 matches before the final, including a record ten successive matches without conceding. Barcelona, on the other hand, had scored 114 goals in all competitions before the final. The two finalists were guaranteed a financial windfall from their progress to the final. Arsenal would receive a revenue of around €37.3m if they won and approximately €34.7m if they lost. Barcelona would earn €31.5m from revenue if they won, and around €28.9m if they were to lose. Included in the total for participating in the final, the UEFA Champions League winners would collect approximately €6.4m, with the runners-up receiving approximately €3.8m. The final marked the appearance of a new trophy following Liverpool's triumph over Milan the previous year. As Liverpool won the competition for the fifth time they were entitled to keep the trophy, creating the need for a new trophy.
Barcelona were expected to line up in a 4–2–3–1 formation, with Ronaldinho, Ludovic Giuly and Deco supporting Samuel Eto'o who would be deployed as the lone striker. They had doubts about the fitness of Lionel Messi going into the final. He had pulled a thigh muscle during the second leg of their match with Chelsea, and had not played since, though he was included in the 22 man squad for the final. Barcelona coach Frank Rijkaard stated he would leave it late before deciding whether to select him. Despite being included in the squad Messi did not feature in the final. Arsenal were expected to line up in a 4–5–1 formation, with Thierry Henry as the sole striker. There was much discussion about whether José Antonio Reyes would take the place of Robert Pirès on the left of midfield. It had been announced before the match that this would be Pirès' last match as he had agreed to join Villarreal next season.
On the morning of the final it emerged that the assistant referee for the game Ole Hermann Borgan had posed for photographs in a Barcelona shirt for Drammens Tidende, a Norwegian newspaper. After initially sticking by the official, UEFA eventually decided to replace him with fellow Norwegian Arild Sundet. Norway's head of refereeing Rune Pedersen stated that "It is an unwritten rule that referees should not do anything that can doubt their impartial stance".
