It's not just about chances. He's totally off form in every other area too. He screws up passes and whatnot. He needs someone to challenge for his spot to hopefully kick some spirit into him.
And he didn't have much service last year either. He still bossed it. It's normal to expect the same this year.
I think you're being harsh on RVP. Whenever he's played he's had Rooney, Welbeck, Young, or Valencia behind him. None are creative.
Rooney has been crap the past 3 games.
I've said it before and I'll say it again. I believe Rooney is world class when he plays up front. I don't like him in the hole. He isn't creative, doesn't face the goal in the 10 spot, and his only move is to pass it to the wingers. When he's on his A game he'll score goals, help out the defense, distribute it out wide from deep, and start good counter attacks, but he'll never create in the hole. He's a number 9 these days.
I don't even have to explain Valencia, Young, or Welbeck. They're only there to do a job at this point.
RVP hasn't been that bad.
