If a player out and out dives or worse, does what Vardy done the other week and actually makes the contact then nail them. If a player makes the most of a foul then blame the officials for encouraging it.
It would be wonderful if refs started giving fouls when players stayed up and then maybe we'd see more players do it. You won't see me criticise any player, even Utd players, for going to ground when they've been fouled whether they could stay on their feet or not though.
And that, right there, sums up everything that is wrong with football nowadays. It's become a sport of Tom Daleys.
