In featuring against the English champions, Casillas made his 152nd outing in Europe’s premier club competition.
He was previously tied on 151 with former international teammate Xavi Hernandez, who made his outings exclusively for Barcelona.
Casillas, who won the World Cup alongside Xavi in 2010, made all of his outings with Real Madrid until this season, when he completed a move to Portuguese giants FC Porto.
When the veteran stopper made the move, eyebrows were raised at Stamford Bridge, as Mourinho questioned the fee paid by Porto for the Merengues legend.
