That was brilliance from Didi. But there was contact.
I'm OK with players inviting a foul and falling, Glenjo is pretty good at it too.
But what I'm not OK with is the feigning injury bit in order to get the other players booked.
He's trying to get the other player booked so that he will stop kicking the shit out of him for the rest of the game. It's actually a very clever move and no different to inviting a foul in the morality stakes.
