"Things are very good for me," Ronaldo told MUTV. "I feel fit and I'm very happy with the way our preparations have gone.
"But I must keep my form going. The Premier League starts soon and I must be ready for that.
"I hope to play well. My ambition is still the same - I want to play well, score goals and provide assists.
"I tried to do the same last year and I worked hard to do that. I hope things come good for me."
