The Portugal winger's revelation that he will spend "two or three days" mulling over his future has been met with short shift by the Red Devils who have stated "he is not for sale" despite massive interest from Real Madrid.
However, speaking after Portugal's Euro 2008 quarter-final failure against Germany, the 23-year-old said: "In two or three days' time I will announce my future because my tournament is over.
"I will speak to United. I will try to reach an agreement and we will see."
Ronaldo is also set for minor foot surgery on a three-month-old injury.
"I have had a small problem for about three months. I'll have the operation and then have a good recovery period," he added.
