If Ronaldo can sustain his level of excellence for another couple of years, you can rate him in that kind of bracket, but at the moment, Its Zidane > everybody else.
What I find humorous is that people are touting Messi as the messiah, but he's failed to sustain his form for a long period of time. It was really only last year 'and shades in 05/06' that he was one of the most promising in the world. Not as influential in 06/07-07/08 as people would like to think, but still enough to keep the punters guessing.
For me its Iniesta > Messi. Just look at the CL final. Iniesta & Xabi ran that game, not Messi.
what level? you were the one few pages back alleged Ronaldo nodding in Rooneys cross against Inter from 6 yards was superior goal compared to Messi goal on the same week when he took on players, played a one-two followed by a great finish.
Last season Ronaldo wasnt even the best player at United, Rooney, Vidic, Fletcher have all had better seasons than him. Iniesta > Messi is more like Rooney > Ronaldo. Both are comparable and it could hold true some matches, but never a theory that would work out among fans and critics along in a season as a whole.
Overall it was a Gerrardesque 08/09 season for Ronaldo in all standards, he should only be rated sligthly better than Gerrard.
If Ronaldo regains his 06/08 form for one or two more seasons he would be rated better than Henry or Ronaldinho, from then on it would take some doing to reach the level of Zidane or Fat Ronaldo. Delivering and dominating in big matches, winnng world cups etc...
Watch the CL final again, Messi was drifting in the middle with his back t wards the net. He forced our defence to play a bit upfield and him occupying our defenders enabled Xavi and Iniesta to move the ball around, else we would've murdered Barcelona like Chelsea almost undid them in the second leg. Messi was the one who was able to maintain his foothold and pass the ball to his team mates whilst the through balls of Xavi, Iniesta and shite of Alves all hitting rent boys, if not for Messi playing in the middle the same trend would've been repeated in the final.
