Yeah, I didn't understand the vitriol directed at Ronaldo when he left. Obviously I was immensely disappointed, as we all were, but at least he went about it the right way. Not once did he have a bad word to say about the club or Ferguson.
Rooney on the other hand....well, I'm not even going to get into it, the little shit is not worth it. Ronaldo was a better player and a better guy too, by the looks of things.
The difference is how they took their words in thought, and timing.
Ronaldo always made his strongest points when its was either summer, or nearing summer transfer market, where it gave the club some time to think about it.
As for Rooney, 'Why now?' replies in the thread is all that's needed to explain.
Another thing is the form of the players. SAF protected both players, and whenever Ronaldo played despited wanting to move, he still bagged goals and still showed class. Rooney? He's been on shit form since World Cup. Ronaldo (as the main spot) got us to two Champions League finals. Rooney, when it was his turn to shine, gave us 2nd place spot in the Premiership, and a knockout against Bayern. Both have earned sliverwares alike, but who made the bigger impact? Ronaldo did.
Third matter comes with their attitudes. Ronaldo was never the one to go around and say "I'll stay in United as long as they want me" et al. Rooney did that, and now wants to transfer. Remember how Ronaldo made some outrageous comments on the first year he wanted to leave? It drove us mad, but if my memory serves me right, he did take his words back and apologized. Rooney, currently doesn't seem to show any signs of that. Not only that, Ronaldo gave time to both club and himself to sort things out, and guess what? He listened to SAF and decided to stay for one more year.
Fourth matter is their history with previous clubs. Ronaldo showed awful lot of respect towards Sporting, and left the club in a very good way. Rooney did not. His ex-club Everton, hate his guts. As someone said earlier, not leaving itself, but how he left. Rooney left traces of disloyalty in the past, and repeating leaves football fans (mainly MU fans) dumbfounded.
Fifth matter is real important. Rooney decides to say "Our team sucks". Who would be happy to say that? I mean, yes we were disappointed when the transfer window closed for not buying big targest, but he should realize that the team -while underperforming- is definitely not 'shit'. Ronaldo to my memory has not said anything as absurd as that.
Sixth matter. Scandal. I don't think I need to go any further in this subject.
To sum it up, it's natural the fans miss Ronaldo, and to be enraged with Rooney.
