The Portuguese star got off to a slow start in Serie A this season, which also saw the superstar being substituted in back-to-back games by manager Maurizio Sarri.
However, Ronaldo has seemingly found his groove once again after bagging his 10th league goal of the season with a superb towering header to seal a 2-1 win at Sampdoria.
"I didn't know that. I'm very happy with the result, it was a very difficult game and Sampdoria played well today," Ronaldo told Sky Sport Italia.
"The whole team showed the right attitude. It was a good goal and I am glad to help the team with another three points.
"I had problems with my knee for a month, but that has gone now and I feel good physically.
"What I want is to help Juve win matches and titles."
