I understand and share your frustration, I just didn't think that was relevant to the overall point you are trying to make. And I was drinking.
I think the scale of decline will have been not as big o a surprise to Henry as we might think. The decline in the quality if the first team and depth if the squad was well underway before he left.
When you look at the way the squad has deteriorated to less than the bare bones you would expect for a top 4 side, the biggest surprise is that we managed to maintain our position for as long as we did.
