Just posted in another thread that I was surprised De Gea wasn't being blamed for us conceding those chances. And here we are.
Henderson does prevent more chances than De Gea. By sweeping more and by claiming more. Not by his sheer presence in the goal magically making our players do better.
In this case sweeping and claiming had nothing to do with it. We conceded those chances because (as anyone who watched the game
should be able to recognise) a lot of our players played like shite.
"Dean would have prevented those chances" is a classic case of people twisting what happened in a game to fit the pre-existing narrative in their head. Maguire and Bailly could have started firing shots at De Gea themselves and someone would have said it was down to Dave not organising them properly.
