The 34-year-old has leveled Raul for the number of sides scored against in the competition, though Lionel Messi is not far behind.
Ronaldo netted in the 88th minute to put the gloss on a comfortable 3-0 win for Juve in Group D at the Allianz Stadium. The goal meant Ronaldo has now scored against 33 different opponents in the Champions League, equalling the record set by Real Madrid great Raul.
Ronaldo cannot afford to get too comfortable, however, as his great rival Lionel Messi has scored against 32 different teams in his Champions League career.
The Barcelona star could level Ronaldo as soon as Wednesday when Barcelona take on Inter – a team against whom Messi has still yet to find the back of the net.
Ronaldo, meanwhile, continues to shine at Juventus as he has started his second campaign with the Serie A side well.
The 34-year-old has scored four goals in seven appearances in all competitions for Juve, with Tuesday marking his first Champions League goal of the season. Last season Juventus surprisingly fell to Ajax at the quarter-final stage, despite Ronaldo scoring in both legs of the tie.
Juventus are back in action on Sunday with a huge early-season league match against Inter at San Siro.
The Bianconeri are searching for a ninth consecutive league title but Inter is setting the early-season pace in Serie A, having won all six of their league matches thus far.
Juve is just two points back of Inter, with five wins and a draw from their opening six fixtures.
