Your convenient blaming of Cooper for everything that is wrong this season is only partially justifiable.
Under his watch we signed Fatawu for a lot of money - one of your key absentees. We also signed El Khannouss, Ayew and Buonanotte (on loan) who have all contributed a lot to our season.
Our shitty signings amount to who exactly? Skipp and Okoli look to be money badly spent. Edouard is a horrible loan deal. Golding was a PSR necessity. That leaves De Cordova Reid, and for free I'd say the jury is out on whether that's a good or bad deal. If he was given enough pitch time, I suspect he'd be an important player for us.
If you're going to add 9 players in a window, especially with the expectation of a points deduction looming, you can't expect a high success rate. We were fishing around in a shitty pool.
On the injuries front, I'd suggest that we've been no better or worse affected than most other sides.
