For one I'm talking about Williams, other peoples mistakes had zero impact on him in that instance.
As for your other point its a game of opinions. Mine is he's a very average stopper and that's it. It's reflected in his career, there's a reason he was at Swansea and never made the jump. Not good enough and we should be aiming much higher.
He's been good for us this season. He's come into one of the league's leakiest defences and helped it become the joint-fifth best.
He's made mistakes. I'm not saying he hasn't.
But there's some utterly ridiculous comments going on in here.
