For so long it wasn't Ronaldo's night, but now, suddenly, it is.
Football's a funny game.
He is now the record goalscorer in men's international football with 110 for his country.
But knowing him, he won't be a happy camper - he's after a win.
Portugal 1-1 Republic of Ireland
James McClean finds himself in space and forces the save from Rui Patricio.
Portugal win a free-kick from the resulting corner.
The Republic need to hold on for a draw now. Five minutes added on.

Ronaldo. There's the record.
It's a classic Ronaldo big-leap-and-pump header after a sumptuous Goncalo Guedes cross.
Portugal 0-1 Republic of Ireland
Ronaldo...Bazunu with the save!
Fairly comfortable for him, but he was still up to the task.
Portugal 0-1 Republic of Ireland
Guess who's standing over the free-kick?
Portugal 0-1 Republic of Ireland
Portugal have won a free-kick on the edge of the area for a handball against Josh Cullen...
Portugal 0-1 Republic of Ireland
Ronaldo picks up the ball and skips in between a couple of weary Irish players, but the less said about his shot the better.
This is a night Ronaldo will want to forget in a hurry.
Portugal 0-1 Republic of Ireland
Goncalo Guedes is on for Joao Cancelo.
Portugal 0-1 Republic of Ireland
Ten minutes left.
Matt Doherty has been through the wars, but he's still there, putting the hard yards in.
His latest clearance falls to Andre Silva, however, but the striker's acrobatic effort is smashed well over.
Portugal 0-1 Republic of Ireland
Jota picks up his head and spots Ronaldo peeling off to the back post, but he's overhit his cross.
Ronaldo then engages in a frank exchange of views with Seamus Coleman.
You don't want to mess with a man from Killybegs, Ronny.
Portugal 0-1 Republic of Ireland
How has he missed?!
Cristiano Ronaldo peels off his man and finds space on the left. His cross finds Bernardo Silva at the far post.
The Manchester City man - who's been lively in this second half - skips past a lunging Matt Doherty but skies his shot from no more than six yards.
Let-offs don't come much bigger than that. No, sir.
Erling Braut Haaland is so close to putting Norway ahead against the Netherlands but strikes the post. It's 1-1 in Oslo.
Portugal 0-1 Republic of Ireland
Joao Moutinho comes on for Joao Palhinha.
A bit of craft and guile added to the Portuguese midfield.
Portugal 0-1 Republic of Ireland
Bernardo Silva dances his way around a couple of half-hearted Irish defenders on the box but his shot cannons into Adam Idah.
They're all back there making crucial blocks and headers.
Big shift from the visitors, but it's going to be a long 20 minutes.
Portugal 0-1 Republic of Ireland
Bernardo Silva cuts in on his left peg and unleashes one straight down Gavin Bazunu's throat.
The Republic are really under the cosh now.
Just over 23 minutes left.
Not many high profile goals in the second half. Austria, Azerbaijan, Israel, Latvia, Malta znd Gibraltar are the only teams to score in the past 20 minutes or so.
Portugal 0-1 Republic of Ireland
The story of Ronaldo's night since that penalty miss?
Blocked shots.
Ali Daei's record still stands...
Portugal 0-1 Republic of Ireland
Bruno Fernandes has not had a great night and he looks less than thrilled as he's replaced by Joao Mario.
Nuno Mendes also enters the fray for Raphael Guerreiro.
Portugal 0-1 Republic of Ireland
ANOTHER chance for Aaron Connolly.
It starts with Josh Cullen charging down Cristiano Ronaldo's speculative effort from distance.
Connolly links up with Adam Idah, who pops down the left wing. He lifts his head to see John Egan (!) in the box, who cushions a header for Connolly, but it goes wide.
There is a suggestion that Connolly was fouled as he went to take the shot, but VAR thought otherwise after a quick check.
