Despite having a combined 792 European Cup/UEFA Champions League matches between them (508 for Real Madrid, 284 for Benfica), these teams have only met three times across the two competitions, and not since the 1964-65 quarter-finals.  

Benfica have won two of the previous three meetings between themselves and Real Madrid (L1), while their one defeat came in the second leg of the 1964-65 quarter-finals (lost 2-1); a tie they still progressed from 6-3 on aggregate.
