The Portuguese has won 76 of the 99 matches he has overseen to date, with just 10 of the remaining 23 games ending in defeat for Los Blancos.
Mourinho's tally of victories means that he has already bettered the win-percentage record previously held by legendary Madrid coach Miguel Munoz and current Barcelona boss Pep Guardiola, both of whom won 70% of their first 100 games at the helm of their respective clubs.
The biggest win of Mourinho's reign so far was an 8-0 demolition of Levante in the Copa del Rey in December 2010 but the undoubted highlight was the club's victory over Barca in the final the following summer.
However, the former Inter boss has managed to come out on top in just one of his 10 head-to-heads with Guardiola, with Madrid having lost half of their games with Barca since his arrival at the Santiago Bernabeu in 2010.
Still, the capital club have won their last 10 games in La Liga and currently stand 10 points clear of the Catalan rivals at the top of the table.
