Oh, not at all saying he isn't ultimately responsible. But there's context that have to be used with facts or, like stats, they are meaningless.
My example would be - and
@EverBlue92 please take this as a response to your post as well - the games away at the big six. Let's say Old Trafford as an example.
We had 14 shots at Old Trafford. We scored one goal. The system, or the style of play, helped us create those chances. We created more chances at Anfield and the Etihad than any other team this season. Scored one goal over both games.
Palace had 4 shots at the Etihad today. They scored three goals and hit the post with the other.
There's the problem. And as it stands, there's only so much Silva can do. He can't run on the pitch and kick the ball in.
Maybe what he now needs to do is to find a way - either from the start or from in-game changes - to ensure we create more chances, because we clearly need more chances to score more goals. We simply aren't clinical enough so, at least for now, it looks like the answer has to be to purely create a higher volume of chances and let the law of averages do the rest.
