"At the moment I feel very good," he told MUTV. "I've scored a few important goals and I want to keep going like that. I want to score more goals.
"But the most important thing is for the team to win games and trophies. We're playing really well and we're in three competitions. Now we need to be strong for 15 more games to finish the season."
Next up for United is Saturday's FA Cup visit of Portsmouth, and Ronaldo feels home advantage gives the Reds a great chance of reaching next month's semi-finals at Wembley.
"Portsmouth are a strong team and always difficult to beat," he said. "But we are playing at home, and I think we have a great chance to go through to the semi finals."
