The 28-year-old forward told reporters: "We scored quickly, things went well, we played well to be winning 4-0, after which we have played more relaxed and slower.
"Satisfied with the game, though we're not at 100%, but we're winning. I try my best to help the team with good performances and goals.
"The season is going well for me but the main goal is to win and to continue at this level."
Ronaldo has now scored 14 goals in the league this season.
