But even if he wasn't feigning injury, I just don't understand what the discussion's even about. If two centre-halves from the same team are watching a ball coming over the top, and collide with each other so that they're laid out flat, and the opposing forward goes through to score, why on earth would the goal be disallowed? Why would there even be discussion about it? I don't see that the difference here is crucial, just because it's the keeper. And by the way, I haven't seen the incident: but did De Gea really have to turn his back on play? That looks to me suspiciously like trying to force the ref's hand.
