He even saw a goal disallowed for offside in the 5-0 defeat at Old Trafford as he tried to give home fans something to cheer about.
But the 36-year-old may have been lucky to have been on the pitch in the second half after he was booked for kicking Curtis Jones.
Such a damning defeat is a result the perfectionist will hate having on his record, especially as Mohamed Salah, one of his new rivals did most of the damage.
In 617 top flight league games, he's only ever lost 5-0 once before, meaning it's the joint-biggest defeat in his career.
And ahead the game there was at least an argument to be had Ronaldo was still in with a shot of being the best player in the Premier League - now there isn't.
The other time? Well, that was a 5-0 loss to inter-city rivals Barcelona when he was with Real Madrid.
Then it was another rival who put him to shame, with Lionel Messi grabbing two assists in a brilliant display, even if he didn't get on the scoresheet.
Ronaldo also got a first-half booking in that game, while he had a teammate sent off - Sergio Ramos - too.
Things aren't going according to plan for Ronaldo since his Old Trafford return and his frustration is already showing.
He was stopped from storming down the tunnel against Leicester by manager Ole Gunnar Solskjaer.
Meanwhile, his kick on Jones against Liverpool was clearly a result of his annoyance at his side's performance.
His high standards won't allow many more results like the one at Old Trafford.
