Just one thing that's bothering me. Davies was booked for a "dive", but realistically he had the choice of diving over the Arsenal player's legs or running full pelt into them and, potentially, injuring both of them. So are referees looking to book players for perceived "simulation" rather than being realistic and just continuing with play. Instead of this he awarded Arsenal a free kick for nothing. Of course it's possible he was trying to win a free kick by deception, but as the referee wasn't deceived, and Arsenal got possession in any case, why the card and free kick. I'm just confused by the way the rules are interpreted.
