He was shocked by the contact that knocked him on his bum. He then proceeded to turn onto his stomach and writhe around inpainshock for a bit longer.
Scared not shocked (Oliver's words).
You're correct they are different but one shows a penchant for doing it in play nearly every time he is near the ball while the other (half his size) bustles his way through and wins it more often than not.
I didn't like what Oliver did and think he definitely overcooked it but one made a mistake and is a tough footballer. The other is a skirt.
Mistakes (plural). Done the same thing twice trying to get a player reported by flopping.
