Why is Ronaldo teasing the fans and media about his 'move' to Real Madrid?

I <3 Man United and Ronaldo (I'm a girl, jeez) and I would be incredibly saddened if he goes. Real Madrid are also trying to get Kaka and I feel that RM are being really greedy. Do you think he will move or is it just stupid games? One minute "My heart is at United". After defeat against Barca, 'I don't know.'
