Ronaldo continued his fine form for the Old Lady after scoring for the fifth successive game to seal a 2-1 victory over Sampdoria to reclaim top spot in Serie A.
The Portuguese forward added yet another impressive goal to his catalogue of career strikes, but even he was left surprised at how high he leaped.
"Seriously, I jumped 2.56 metres? I didn't realise that. I'm really happy with the result," he told Sky Italia.
"It was a very difficult game and Sampdoria played really well. The whole team showed great character – it was a good goal and I'm happy to have helped my team to pick up the three points."
Sampdoria president Massimo Ferrero joked that the five-time Ballon d'Or winner should've been booked for leaping that high.
"The team are there, we saw that yesterday against Juve," he said.
"I must say that Ronaldo had to be booked after that leap. It was as if he was taking off like an airplane! Cristiano won the game, but my boys defended well."
