I'd argue that his presence contributed in part to the alarming drop offs in the rest of the forward line. You just have to look at how often he demands the ball and how often our players defer to him to their own and the team's detriment.
Even this season, when Ronaldo doesn't play, we score more, and all of the front line look like they could grab a goal; conversely when he plays, he struggles to score, and everyone else (including those that do well in his absence) struggle as well.
Same thing happened last season, the difference was he was scoring. I'm not saying the others should be absolved of any responsibility when it comes to how shocking their performances were, but Ronaldo in the team is detrimental to everyone else.
If you demand every ball in the final 3rd, you'll outscore everyone, doesn't mean he didn't miss a shedload and cost us points
