#2 Real Madrid
Between the 1997/98 season and the 2003/04 season, Real Madrid won the trophy on three occasions under Jupp Heynckes and twice under Vicente del Bosque.
For 7 successive seasons, between 1997/98 and 2003/04, the club reached the quarter-final stage of the tournament and at the time, matched Manchester United's similar feat that ended a year earlier and tied the record.
The club, now under Zidane, is set to take on PSG in the round of 16, in an all-important tie - one that if they lose, will end all hopes of breaking their own record.
Between the 1997/98 and 2003/04 run, other managers such as Guus Hiddink, Carlos Queiroz and John Toshack were also in charge of Madrid and were involved in this fantastic feat.
Notably, the two-time defending champions are the most decorated club in the history of the competition with 10 titles to their name.
