Totti turned 38 last weekend and he made sure he would remember it as he scored against Manchester City to level the game at 1-1 -- Sergio Aguero having given the hosts the lead with a penalty -- to break Ryan Gigg's record set when he was 37 years and 289 days old.
The game finished 1-1 yesterday, a result that is of more help to the Italian side than the English champions.
"When you talk about Totti, you can only say really banal things (in comparison with what he does)," said Roma coach Rudi Garcia.
"I took great pleasure from his goal today. His talent is what made the difference in front of the goalkeeper. I hope it's the start of a fantastic story for Roma."
However, the 34-year-old was unable to help turn around a gripping encounter as the French champions prevailed 3-2 at the Parc des Princes to split the group wide open.
PSG -- who were only denied a semi-final spot by Barcelona on away goals two years ago -- top the group on four points with Barcelona a point back while Ajax, who were held 1-1 by APOEL Nicosia, are third on two points.
