It's in all our interests that he succeeds and I can't understand why anyone would think differently, but objectively (these particular stats actually don't lie as we've seen it on the pitch with our own eyes) his record is pretty poor. He hasn't been dealt the best hand by any means, and that's an understatement, but he's playing it very poorly again, and again, and again.
He needs to learn and change and stop trying to bluster and bullshit all the time. The results will define you Luke. You need to try something different to get them. It's unlikely, if not impossible, to happen magically by more of the same. It's been a long long time of churning out crap on the pitch with the odd uptick when you, and they, seem to be arsed.
