A look at the clubs with the most entries into the world's most prestigious club competition.
For European clubs, qualifying for the UEFA Champions League represents the pinnacle of achievement. The global audience, substantial prize money, and prestige of competing make it a primary goal for teams across the continent - from powerhouse leagues like the Premier League and LaLiga to less prominent domestic competitions.
The list of teams with the most appearances is a who's who of European football royalty: traditional, powerful clubs that have often dominated their national leagues. Unsurprisingly, Real Madrid, the competition's most successful team, also holds the record for the most participations. Following them is two-time winner Benfica, with four-time champion Ajax rounding out the top three.
