I've watched it dozens of times from every angle. The pixels on your screen must configure themselves in a different way to mine. What I see, and bear in mind at full speed both players were flying with virtually no time to even think about a contrivance, is a player round the keeper and not so much as a 1/20th of a second later that keeper's swiping right leg take him out across the bridge of his left foot. Sergio doesn't stick his leg down or sideways to initiate contact. Nor does he jump particularly high, but then again he's not obliged to. It's not up to him to get out of the way of ill judged challenges. It's the most stonewall penalty imaginable
