The thing that disappoints me about Rooney is that he never fix his off form habits, with him being in the team for so long he should really fix all this mood mambo jumbo and learn to keep his personal mood in-check like a true professional. Sure you can have off form, it's normal, but Rooney have been having too many of those off form runs, and to be honest, he's not worth to be the highest paid player in the squad with that kind of productivity.
We're always cutting him some slack, conjuring up excuses left right center (e.g. work rate, heartbeat, linking up, passion, sacrificed out of position, coming from injury, having purple patches one too many, yadda yadaa) while Truth be told, he's just not world class, and getting further away from that direction.
My guess is that the reason most of us are so heartwarming on RvP is that because after Ronaldo left, finally we have someone to rely on in the striking department than Wayne Rooney.
I won't be felt hard done if he's sold, time for him to move on and find that extra drive if he can't seems to find one in United, if the arrival of RvP can't seem to motivate him at the age of 27, I don't think he'll ever gonna be achieving anything greater than what he has, and i can only see decline in the near future.
