The 24-year-old's crucial stop was then magnified insurmountably as less than five minutes later his side had the lead.
And this is how they thank us!'
Ronaldo had earlier drawn Madrid level with his 100th Champions League goal for the club from the penalty spot on the stroke of half-time, cancelling out Adrien Rabiot's opener for the French side. The Brazilian ace has been continuously linked to a move back to Spain with the Los Blancos with some reports also claiming that a deal is already in place between the player and the club.
It's one thing to praise him for stripping his game down to its essentials, for adapting to the ageing process, but there comes a point at which he is so uninvolved in the game that, even with his remarkable propensity for goals, he becomes a hindrance (even if his ruthlessness offered a nice counterpoint to Neymar's look-at-me fripperies). Because in these huge one-off games when their future is at stake, and in their competition of choice, Madrid's players work harder.
Ronaldo then equalised when he did the honours from the 12-yard mark in the 45th minute.
"Today, I stood out, I helped the team to win by scoring two goals, but we know that the tie is not finished yet".
A quiet game by the Brazilian's standards was met by a decisive performance from Ronaldo. "We played with a lot of character", he said.
The Ronaldo of 2018 is, of course, much changed to the beast we witnessed from 2010-16. Perhaps Ronaldo, operating within an ever-decreasing sphere of influence, will hit another purple patch and Madrid will enjoy Champions League redemption after an otherwise miserable season.
Neymar (PSG) and Cristiano Ronaldo (Real Madrid) embrace at full-time.
However good or not the performance was, PSG lost. "He has always shown he can make the difference".
While Real are looking to win the European Cup for the third year running - something no club has done since Bayern Munich in 1976 - and the 13th time overall, PSG risk seeing their wait for a first Champions League crown go on.
The change was almost instant as Madrid gained enough of the key possession with Asensio providing the deliveries for Madrid to unearth two goals.
And Spanish publication Marca widely praised the coach.
As the second half began, Kylian Mbappe reminded the world of his phenomenal young talent by drawing a smart save from Keylor Navas at the start of the second half.
But one man who was not surprised to be mirroring the joy of his teammate was Marcelo, who just three minutes after congratulating Ronaldo was receiving the plaudits himself after arrowing a left-footed volley, with the help of a slight deflection, past the beaten Areola, sending the Madridistas behind the goal into scenes of delirium.
