He's keeping his balance, both arms are equally out, looking forward at the ball and if anything g raises his elbow as it to trouble and go over silva (with the height difference of about a foot between them).
As soon as contact made he's bringing his hands up before the wistle is even raised.
As unfortunate, horrible and effing painful as it is, I didn't think anything of it either first time or on replays.
Will be back on Tuesday with a face mask no doubt....
Ouch!
