European Champion Clubs' Cup in the context of "FC Bayern Munich"

Amsterdamsche Football Club Ajax (Dutch: [ˈaːjɑks]), also known as AFC Ajax, Ajax Amsterdam, or commonly Ajax, is a Dutch professional football club based in Amsterdam, that plays in the Eredivisie, the top tier in Dutch football. Historically, Ajax (named after the legendary Greek hero) is the most successful club in the Netherlands, with 36 Eredivisie titles and 20 KNVB Cups. It has continuously played in the Eredivisie since the league's inception in 1956, and along with Feyenoord and PSV Eindhoven, it is one of the country's "big three" clubs.

Ajax was one of the most successful clubs in the world in the 20th century. According to the International Federation of Football History & Statistics, Ajax was the seventh-most successful European club of the 20th century and The World's Club Team of the Year in 1992. According to German magazine Kicker, Ajax was the second-most successful European club of the 20th century. The club is one of five teams that have earned the right to keep the European Cup and to wear a multiple-winner badge. In 1972, they completed the continental treble by winning the Eredivisie, KNVB Cup, and the European Cup. They also won the first (albeit unofficial) European Super Cup against Rangers in January 1973. Ajax's most recent international trophies are the 1995 Intercontinental Cup, 1995 UEFA Super Cup and the 1995 Champions League, where they defeated Milan in the final; they lost the 1996 Champions League final on penalties to Juventus. In 1995, Ajax was crowned as World Team of the Year by World Soccer magazine.

The 2025 UEFA Champions League final was the final match of the 2024–25 UEFA Champions League, the 70th season of Europe's premier club football tournament organised by UEFA, and the 33rd season since it was renamed from the European Champion Clubs' Cup to the UEFA Champions League. It was held at the Allianz Arena in Munich, Germany, on 31 May 2025, between French club Paris Saint-Germain and Italian club Inter Milan.

Paris Saint-Germain won the match 5–0 for their first European Cup title, marking the second final victory by a French club since Marseille in 1993. Their margin of victory was the largest in any of the main European men's club competitions final, with their goal tally only surpassed in one European Cup final by Real Madrid's seven in 1960. In doing so, Paris Saint-Germain completed a continental treble, the first of a French club, while Luis Enrique became the second manager since Pep Guardiola to have won the treble twice. As winners, Paris Saint-Germain earned the right to play against Tottenham Hotspur, winners of the 2024–25 UEFA Europa League, in the 2025 UEFA Super Cup, and automatically qualified for the 2025 FIFA Intercontinental Cup final and the 2029 FIFA Club World Cup. The match would also be Simone Inzaghi's final match as manager of Inter Milan as he would leave his post three days after the final by mutual consent.

The UEFA Champions League is a seasonal football competition established in 1955. Prior to the 1992–93 season, the tournament was named the European Cup. The UEFA Champions League is open to the league champions of all UEFA (Union of European Football Associations) member associations (except Liechtenstein, which has no league competition), as well as to the clubs finishing from second to fourth position in the strongest leagues. Originally, only the champions of their respective national league and the defending champions of the competition were allowed to participate. However, this was changed in 1997 to allow the runners-up of the stronger leagues to compete as well, and again in 1999 when third and fourth-placed teams of the said leagues also became eligible. In the Champions League era, the defending champions of the competition did not automatically qualify until the rules were changed in 2005 to allow title holders Liverpool to enter the competition.

Teams that have won the UEFA Champions League three consecutive times, or five times overall, receive a multiple-winner badge. Six teams have earned this privilege: Real Madrid, Ajax, Bayern Munich, AC Milan, Liverpool, and Barcelona. Until 2009, clubs that had earned that badge were allowed to keep the European Champion Clubs' Cup and a new one was commissioned; since 2009, the winning team each year has received a full-size replica of the trophy, while the original is retained by UEFA.
