melonhead if you grab a shirt lightly and the man waits half a second before pretending to be tripped? is that still a foul?
Yes. Because the player has been impeeded. The dive happens because refs give virtually nothing unless you go to ground. The fact is Pearce tugged his shirt when Afobe had beaten him. Penalty, end of. Whether its always given, often given or rarely given doesn't stop it being a foul.
