Playing devils advocate here, but imagine how we would feel if we were in the Championship (as we were in the not too distant past) and we were level on points with the second placed team but behind on goal difference on the last day.
We are away to someone like Burnley or Bristol City, we win but the second placed team also win, scoring the winner with the last kick of the game (like Man City did) to secure automatic promotion.
The Burnley/Bristol City fans stay and celebrate, taunting us. Can you imagine the meltdown on here if that happened?

Everybody would be slagging off the oppositions fans, calling them smalltime, a nothing club etc and there would be a permanent grudge against that club.
Now I can see where Rooney is coming from. He's still a big fat headed selfish granny shagging twat though and no doubt he'll make his comeback in the final group game at Euro 12 only to get sent off.
