From an early camera angle (that I haven't seen repeated) it suggested the Young "penalty" actually started outside the box - and the replays I saw the foul is already started from the beginning of the replay
Valencia should probably have got a red - but Lovren should have got two yellows at least (one for the nasty elbow against the back of McTominay's neck which looked nasty and completely in-necessary)
Was never a hand ball, as his arm wasn't in an in-natural position given he was still getting in position- ie wasn't standing still - and his arm didn't move towards the ball. Ball to arm not arm to ball
