I think people are really overstating how poor Rooney has been, to me it's looked clear that he is still a level above what we have in the rest of the team even though he is out of form.
He'll continue to give the ball away in a dangerous position once or twice per game, but he's done that for most of his career and I don't really expect him to change that now.
He's not a winger though, and if we aren't going to play him up top or in an attacking midfield role then we should bench him and use him as an impact player.
