Sergio Ramos is a captain for the Champions League

Iker Casillas left Real Madrid in order to join Porto in the summer of 2015 and not only did the goalkeeper leave a void between the posts, but he also left the captain’s armband up for grabs behind him.

That honour, by way of seniority and service, went the way of Sergio Ramos, who had moved to Los Blancos a decade earlier and who has since led the club to two more Champions League titles.

When Ramos took over, Los Blancos had just given up their Champions League crown won in Lisbon with a defeat against Juventus at the semi-final stage of the competition.

Since then, though, Real Madrid haven’t felt the feeling of being eliminated from the Champions League.

They’ve won two titles in a row, winning in Milan and Cardiff against Atletico and Juventus, respectively.

Their latest victory came against a multi-millionaire Paris Saint-Germain side, who were actually favoured to progress before the tie began.

Their list of victims is very impressive, as Roma, Wolfsburg, Manchester City and Atletico were beaten in 2015/16, then Napoli, Bayern Munich, Atletico and Juventus fell the following year, before PSG were humbled this season.

Victory over the French side has completed the run of teams seen off by a Real outfit led by Sergio Ramos, who has not missed any of the life-or-death encounters since assuming the role of Real captain.

The free-scoring Parisian outfit intimidated many going into the draw due to their attacking trident of Neymar, Kylian Mbappe and Edinson Cavani.

However, they just managed to score two goals, one through Adrien Rabiot and a rebound from Cavani to bookend Real’s five strikes.

It is true that the Brazilian could only play in the first leg and his replacement Angel Di Maria didn’t quite hit the heights expected of him.

PSG’s attackers are the latest in a list of strikers who have been unable to shoot down Ramos and co.

Other elite forwards such as Robert Lewandwoski, Sergio Aguero, Antoine Griezmann, Gonzalo Higuain, Paulo Dybala, Mohamed Salah and Dries Mertens all felt the same frustration at being unable to end Real’s grip on the trophy.

During the almost three years that Zinedine Zidane has been in charge, the numbers are scary: 17 wins, four draws and just two defeats (against Wolfsburg and Atletico, both of whom were eliminated in separate 3-0 wins thanks to Cristiano Ronaldo hat-tricks).

The scoring balance is also very much in their favour, scoring 46 times (averaging two per game) and only conceding 18, which is an average of less than one in each game.

As if that weren’t enough, Ramos has also scored two goals in these games.

Beyond his defensive reliability, always at his best in the biggest games, he loves to contribute in attack.

His finest hour perhaps came in Milan, where his vital goal against Atletico was fundamental in bringing the tie to a penalty shootout.

With Real Madrid now through to the quarter-final this year, the team captained by Ramos will fight to achieve their most difficult triumph yet.

Last season, they became the only team in history to repeat as Champions League winners since the competition shifted format.

Now, they can increase their legend in a tournament that their Captain Champions particularly loves.

It is clear that no opponent wants to be drawn against the most reliable team in Europe in recent years.
