A Champions League record will be broken by Real Madrid this season if Los Blancos make it to the last four, as it would be a record seventh consecutive semi-final.
In the past six years they have always been at least one round away from the showpiece event, reaching it twice with wins over Manchester City and Bayern Munich and falling at that hurdle four times with defeats to Juventus, Borussia Dortmund, Bayern and Barcelona.
Only the Blaugrana have made it past the quarter-final stage that regularly in the history of the European Cup and Champions League, something they achieved between the 2007/08 and 2012/13 seasons, but that can be surpassed if Los Blancos overcome their next two-legged tie.
Bayern are on an impressive run of consistency too and are within touching distance of what would be their sixth straight semi-final.
Yet the German side remain well behind Real Madrid in second place on the list of the most semi-finals ever contested, as the Spanish side have already featured in 27, while the Bavarians have done so in 18 and Barcelona in 15.
