The Madrid thing was completley diffrent from his Santo situation, he was aking for a new contraact months before the summer and was told by Real that they would speak to him when the season finishes. When the season finished they decided to go for Tranadlo and refused to negotiate. Then when Real knew they could get him it was back to Robinho, if that happened to me in my job and be leaving no matter what aswell!
There is no problem leaving his job when you are unhappy.
But go to the press and refuse to play like he did was pretty childish.
Say that he was used as a makeweight to Ronaldo transfer was very a confortable excuse to him at that moment.
And I have info that he cried and threatened to abandon football on the last day off the window meeting.
Common you can't take that serious. He is not a fool, he is advised by a very smart manager.

Who would do everything to make money on a transfer.
Off course Madrid are not saints either, they could have denied everything he was asking and threatening him to stay a whole season attached to his contract and playing for reserves or something like that.
But that is not the point,
The point is that Robinho is not a very good character, he may look like that, with jokes and everything,
but you can expect anything from him.
Don't be surprised if he do it again.
Now let's get back on topic
