Great analysis. As you say, his ability to shift momentum back to his left in a fraction of a second (at his age, no less) is the most remarkable thing about this, and supports the old adage that it’s a goalkeeper’s feet, not his hands, that are most important. On the flipside, the reaction speed of his left hand is also incredible, but I don’t think that can be learned- you have it or you don’t!
A goal saved is the same as a goal scored. Long live the King.
