Ronaldo refused to celebrate after burying his first-half header.
"I did not celebrate the goal because it is a home where I played six years and I was there from almost childhood. It is not right to celebrate, I want to win but respect the people there.
"We created opportunities and could not take advantage, but this is open. Let's go to Old Trafford and we'll have options there to score. It's okay.
"We will not have to change the plan, we always took the initiative and we will try to win the game at Old Trafford. I hope that Madrid can win."
