Its not even close, David got caught but he would have got up and played on if he was looking the right way, there is a full thread of your own supporters saying as much over in the United forum. Coady was caught and genuinely hurt, Liverpool also didn't have to put the ball out they chose to. Had Salah scored it would have been a similar situation and no one would bat an eye. Not the same scenario at all. One was hurt, one wasn't the length of treatment and reactions after show the truth.
Liverpool stopped it not the ref.
Who says he would have got up? Have you seen many players suffer studs down the Achilles just pop up? This is my point, you will not see players pop up after bad challenges to the ankles, it does not happen.
And fair play Liverpool, a bit of sportsmanship. Would have been easy to whip a ball in on top of the keeper but choose not to. The only difference there is Coady is lucky they aren’t facing Arsenal while David was.
Look at Coady, up running about a few minutes later, couldn’t have been that bad etc etc.
Can’t believe he wasn’t following the ball when he was down injured and didn’t know where the play was.
