United have taken a bullish stance over Real Madrid's aggressive pursuit of the Portuguese superstar, briefing over the weekend that Ronaldo (left) was starting to accept he will not be allowed to leave this summer.
But a close friend told the Mirror: "Ronaldo has made his mind up now and feels it is just time to wait before he announces what he will do - which is to go to Madrid."
Real are prepared to plus Brazilian attacking midfielder Robinho once Ronaldo clarifies his intention to quit English football.
And he has made it clear that United's tactics will not work.
"The announcement about Cristiano's future will be the next step, but it won't happen until the end of Euro 2008 for him and Portugal," added the insider.
"At the moment he's trying to work out what United are playing at and why they're saying what they're saying, because it's simply not right.
"He is determined to be the master of his own future.
"The decision has been made and now it's a case of everybody getting in position for the future - even if United aren't yet ready to sit down and talk to Real."
