Yeah. I think people might be confusing "brave on the ball" with "good on the ball". He's definitely brave to take the ball on in those positions, but it's not necessary. What we really need is a press resistant keeper who just generally has excellent distribution.
Onana was excellent in the CL final, even better than Ederson (who is widely regarded as the best in the world at distribution) at beating the press. If you haven’t, then watch that, not the old reel of extreme cases of him coming off his line.
I would argue what makes the best keepers good on the ball is the combination of technical ability and bravery/composure. No point being a great passer if you poo yourself the moment you are pressed, or not brave enough to leave your own box.
What makes a sweeper so effective in the modern game where is the keeper becomes an additional outfield player, making it a lot harder to press. This is the primary reason we are so easily pressed and dominated in games against Man City, Liverpool and Arsenal because they are the best pressers in the league and we have De Gea who cannot play this role.
ETH consistently has said he wants us to dominate games more and to do so, we need a keeper that is technical enough and brave enough to be our 11th outfield player when in possession. This is why I find it hard to comprehend that we would even want De Gea as a back up at this point, as he on his own changes the system.
