Possibly. But I like Keane much better than Rooney, both as a man and a footballer, so it would be an odd sort of bias. I like Rio better too, for that matter. To me all three instances are, well, a bit irrelevant, really: Players angling for more money one way or another - threatening to leave one way or another. Footballers tend to do this, it's a fairly common occurence.
I don't consider it important. They didn't leave - and that's that. I find it almost bizarre to actively dislike a player because of some contract shenanigans that happened years ago. There's likely many more incidents of a comparable nature we don't know about - and I don't care about those either. My opinion of Player X wouldn't change in the slightest if it turned out that he too "held the club ransom" at some point or other.
But, like I said above, I very much prefer to look at these players as just that, players - which means that I don't really give a feck about what they do behind the scenes as long as the latter isn't positively harmful to the club. And if it is, I expect the manager to deal with it. Fergie sanctioned Rooney's new contract, Rooney apologized to his team mates - and, what? End of story for me.
Ronnie would spend the whole time asking if his hair looked OK
