Context: The 2009–10 DFB-Pokal was the 67th season of the annual German football cup competition.  It commenced on the weekend around 1 August 2009 with the matches of Round 1 and ended on 15 May 2010 with the final which is traditionally held at Olympic Stadium in Berlin.  Since the cup winner, Bayern Munich, also won the German championship and the runner-up, Werder Bremen, qualified for the Champions League, VfB Stuttgart, the sixth-placed team of the championship, qualified for the 2010–11 UEFA Europa League third qualifying round instead. The 2017 UEFA Champions League Final was the final match of the 2016–17 UEFA Champions League, the 62nd season of Europe's premier club football tournament organised by UEFA, and the 25th season since it was renamed from the European Champion Clubs' Cup to the UEFA Champions League.  It was played at the Millennium Stadium in Cardiff, Wales on 3 June 2017, between Italian side Juventus and Spanish side and title holders Real Madrid, in a repeat of the 1998 final.  Real Madrid won the match 4–1 to secure their 12th title in this competition.  With this victory, as the defending champions, Real Madrid became the first ever team to successfully defend their title in the Champions League era, and the first to do so since Milan in 1990.  On the other hand, Juventus lost a fifth final in a row and a seventh in nine finals reached. The 1957 European Cup Final was a football match which took place at the Santiago Bernabéu Stadium in Madrid, Spain, on 30 May 1957.  It was contested between Real Madrid of Spain and Fiorentina of Italy.  Real Madrid won 2–0 after goals from Alfredo Di Stéfano and Francisco Gento in the second half.  It was the first of four finals (also counting the Champions League era, followed by the 1965, 1984 and 2012 finals) where one of the teams played in its home stadium, and also the first final where the winning team played at their home stadium. The 2001 UEFA Champions League Final was a football match that took place at San Siro in Milan, Italy, on 23 May 2001, to decide the winner of the 2000–01 UEFA Champions League.  The match pitted Bayern Munich against Valencia.  The match finished in a 1–1 draw, but Bayern clinched their fourth title by winning 5–4 on penalties.  This was also their first European Cup title in a quarter-century, also representing Valencia's second consecutive final defeat (2000 and 2001).  Due to all the goals scored by penalties and the penalty shootout needed to decide the winner, this UEFA Champions League match became an "all-penalty" final and the only one ever to happen to this day.  The 2001 final saw the two previous seasons' losing finalists clash, Bayern Munich lost to Manchester United in the 1999 final and Valencia lost to Real Madrid in the 2000 final. The knockout phase of the 2009–10 UEFA Champions League began on 16 February and concluded on 22 May 2010 with the final won by Internazionale against Bayern Munich 2–0 at the Santiago Bernabéu Stadium in Madrid.

Real Madrid won 1–0, the only goal scored by Predrag Mijatović, to clinch their seventh European title, their first for 32 years.  The repeat of the match was played in the 2017 UEFA Champions League Final in Cardiff, which Real Madrid won 4-1. The 2009–10 DFB-Pokal season came to a close on 15 May 2010 when Bayern Munich played defending champions Werder Bremen at the Olympiastadion in Berlin.  Bayern thrashed Bremen 4-0 with goals from Robben, Olić, Ribéry, and Schweinsteiger.  The title capped off a successful season, with Bayern winning the domestic double of the Fußball-Bundesliga and the DFB-Pokal.  These successes were Bayern's 22nd league and 15th cup titles.  Bayern were also in line for "The Treble" but lost to Internazionale of Milan, 2-0 in the Champions League Final at Madrid's Santiago Bernabéu Stadium on 22 May.

The final was played on 22 May 2010, at the Santiago Bernabéu Stadium, home ground of Real Madrid, in Madrid, Spain.  The final was won by Italian club Internazionale, who beat German side Bayern Munich 2–0.  Internazionale went on to represent Europe in the 2010 FIFA Club World Cup, beating Congolese side TP Mazembe 3–0 in the final, and played in the 2010 UEFA Super Cup against Europa League winners Atlético Madrid, losing 2–0. The 2010 UEFA Champions League Final was a football match played at the Santiago Bernabéu Stadium, home of Real Madrid, on Saturday, 22 May 2010, to determine the winners of the 2009–10 UEFA Champions League.

The refereeing team came from England and was led by Howard Webb.
