His Southampton team did exactly the same thing in Division one so there is no chance he will fine players, he is probably more likely to be rewarding / praising them for doing it
From my viewpoint it looked like the Reading player knocked the ball past Greer who was in close proximity and then ran into Greer giving him no opportunity to get out of the way (as he was so close at the time) and then hit the deck looking for a foul.
Maybe Greer turned his body as some...
