imo mark if a player and i stress that ANY player is consistently in the refs face arguing with the decision right or wrong its a booking. players need to show respect to the ref because his decision is final. resoect is shown to the refs in rugby because if they argue with the ref the ref has the power to send off a player or if its a free kick, the free kick brought 10 metres forward. its about time football refs start growing some balls and start being harsh to players. if all refs did that then maybe just maybe more respect from the players might be shown
mascherano deserved to be sent off imo
