In answer to the original question: no, I never want to see him in a QPR shirt again.
He didn't even have a particularly good season in 2011/12, only coming alive in the last handful of games. And then he lets us down in our most important game for more than a decade by self indulgently reverting to the thuggery that has been a feature of his life to date. Plus, based on what I've heard, he's a disruptive influence in the dressing room. He's too wrapped up in himself, nothing else matters, otherwise he wouldn't have gone anywhere near that nasty little Tevez.
How many more reasons do you want? How any more chances are you going to give him to let down the club, his fellow players and us, the fans.
No, no and again, NO!
