Atlético Madrid, a top Spanish football club based in Madrid, competes in La Liga and plays its home matches at the Riyadh Air Metropolitano. Founded on 26 April 1903 as a youth branch of Athletic Bilbao, the club adopted its iconic red-and-white striped shirts in 1911, a change possibly inspired by cheap mattress ticking or kits purchased from English clubs like Southampton. Known as Los Colchoneros (mattress makers), Atlético has won 11 La Liga titles, 10 Copa del Rey trophies, and three UEFA Europa League titles (2010, 2012, 2018), while reaching the Champions League final in 1974, 2014, and 2016. The club's honorary president is King Felipe VI, and it maintains a fierce rivalry with Real Madrid in the Madrid derby. With a rich history of domestic and European success, Atlético remains one of Spain's most successful and passionate clubs.
