The Madrid derby clash between Atletico Madrid and Real Madrid is one of the biggest fixtures in European football.
The two Madrid clubs, along with Barcelona, are the dominant forces in Spanish football history and they have produced some memorable matches in both La Liga and the Champions League.
Here is all you need to know about the Madrid derby, also known as El Derbi Madrileno.
The Madrid derby is played out twice a season in La Liga, with each team hosting one fixture. There is also the potential for additional meetings between the sides in domestic or European cup competitions such as the UEFA Champions League or Copa del Rey.
El Derbi Madrileno is usually split across two venues, with Atleti's home games played at the Metropolitano and Real's at the Bernabeu.
Their Super Cup meeting was held in Saudi Arabia, at Riyadh's Al Awal Park at King Saud University, while they have also famously clashed on neutral territory in two Champions League finals.
The first of those came in 2014 at Lisbon's Estadio da Luz, before they met again at Milan's San Siro in 2016.
Both La Liga and Copa del Rey meetings between these sides are available to watch on bet365's Sports Live Streaming service.
If they are to meet in the UEFA Champions League, the action will be shown on TNT Sports.
Real Madrid have traditionally had the upper hand in their rivalry with Atletico and the first 173 La Liga meetings between the pair - as of July 2024 - have featured 91 wins for Real, 41 victories for Atletico and 43 draws.
Real's La Liga success in 2023/24 was their 36th league title, a record in the Spanish top flight, while 2020/21 champions Atletico are third on that list with 11 titles.
Several players have represented both Atletico and Real Madrid over the years - including the man after whom Real's stadium is named.
Santiago Bernabeu, a Real stalwart both as a player and club president, made one official appearance for Atletico in 1920, while more recent stars who played for both teams include prolific Mexican striker Hugo Sanchez and German midfielder Bernd Schuster, who also spent eight seasons at Barcelona.
Santiago Solari moved from Atletico to the Bernabeu in 2000 and was part of Real's 'Galacticos' era, winning two La Liga titles and the 2002 Champions League.
Spain internationals Jose Antonio Reyes, Alvaro Morata and Marcos Llorente have also crossed the divide and Belgium goalkeeper Thibaut Courtois has enjoyed great success with both Madrid clubs.
Courtois won La Liga, the Copa del Rey and the Europa League as an Atleti player, before establishing himself as a key man for Real, claiming two more league titles and being named man of the match in the 2022 Champions League final victory over Liverpool.
The top 10 goalscorers in the Madrid derby include some legendary names from Real's history, including Alfredo Di Stefano, Raul, Ferenc Puskas and Emilio Butragueno.
Way out in front, though, is Portugal superstar Cristiano Ronaldo, who scored 22 goals against Atletico during his nine seasons in Spain, including a hat-trick in the 2016/17 Champions League semi-final first leg at the Bernabeu.
Atletico's leading derby scorer is Paco Campos, who was born in the Canary Islands but who made his name in the Spanish capital with nine league goals and three more in cup competitions against Real in the 1940s.
Former Real Madrid captain Sergio Ramos has made the most derby appearances with 43.
That was one more than fellow former Real players Paco Gento and Manolo Sanchis, while Los Colchoneros' record appearance maker is current captain Koke, who has faced Los Blancos on 38 occasions.
