OMFG
Go through the De Gea Performance thread, circa June/July 2023, for yourself. It was one pisstake after another how De Gea destroyed our attacks and how Onana, being a proper modern keeper, would "transform" our attack.
It was never just about helping with the buildup phase and the recycling of possession, but since this is now what we're shifting to as the reason for bringing in Onana, we are undeniably worse in our buildup play and recycling of possession. I will not blame Onana for the deterioration of our buildup and possession, but no sane person will argue that United have improved their buildup and possession play since the arrival of Onana.
At least not so far. And that's the point, the point being that our previous keeper was what was holding back our buildup and possession play. De Gea's howlers were reason enough to let him go, but apart from being at least a wash in terms of shot-stopping, the entire rationale for Onana was that he would improve our performance overall with superior buildup play and recycling of possession. That has only not happened, we are undeniably worse at both than we were last season, although I want to be clear that Onana shoulders none of the blame for that. The point is that it was hilariously, and pathetically, claimed here that if we just got rid of De Gea -- and getting rid of De Gea was how it was often described here -- that we would dramatically improve our buildup play and recycling of possession, and thus our attack. Even the lovechild of Ray Charles and Stevie Wonder can see that that has not happened.
