What I like about his last matches, not just a few either, is that he is settling to a solid level. He still makes some very strange moves - at least two or three of the shots he takes a step the wrong way which makes a simple save look strange. However, he deals with everything that we expect him to deal with, and that is a very good base-level to be at.
Also, I love his pause on the ball when playing out from the back, just getting the attacker to move a stride, and then Onana releases to a different player, completely flat footing the attacker and removing his momentum. It's one of those subtle but very important elements of his from playing out from the back. He creates space where there is none.
