Atlético has played at the European stage regularly since its 1958–59 European Cup debut, subsequently entering the UEFA Cup Winners' Cup (1961–62), the Inter-Cities Fairs Cup (1963–64), the UEFA Cup (1971–72) and the UEFA Super Cup (2009–10). Starting with the 1999–00 relegation Atlético did not qualify for European competitions for seven years, but from the 2007–08 season, it has taken part in either the Champions League or the UEFA Europa League every year, enjoying success in both competitions.
