The Premier League has always attracted big name players. Players who we want to grace our shores and entertain football fans across the country, and players who provide those moments of inspiration to our young footballing wannabes.
However, Diego Costa does not, in any way shape or form, fit that bill.
Football has always been subject of ridicule from rugby fans, and with evidence from Stamford Bridge on Saturday, it's hard to argue. Costa set his stall out early. In the first few minutes he moved forward with the ball and had his leg brushed by the backtracking Francis Coquelin. Costa fell to the floor, sat up, and brandished the imaginary yellow card to the referee.

Then came the debacle near half time. Costa challenges angrily and with gritted teeth to get the ball, but goes too far when he pushes Laurent Koscielny in the face and then follows it up with a flailing forearm. A red card offence in itself some would argue.
Not content with that, in an animal like show of masculinity, he barges Koscielny to the floor - a further yellow card maybe? In steps Gabriel and Costa turns on him.

In an attempt to diffuse the situation, the referee produces a pair of yellow cards, that should have been the end of the matter. But, moments later, Costa's over aggressive master plan is complete. He gets into the ear of Gabriel, who is now sporting some glowing red scratch marks on his neck, and Brazilian reacts - petulantly raising his leg behind him, presumably towards Costa. His actions cost him a red.
So into the second half, and Costa's frustration builds. Alex Oxlade-Chamberlain pinches the ball from him and Costa reacts by kicking out at him - another yellow?
Some say that Jose Mourinho's management was superb by then withdrawing Costa from proceedings. Even the most inexperienced of Sunday league managers would have made that call. Nevertheless, a call that keeps Chelsea with a man advantage.
There is no doubt that both red cards received by Arsenal, by the letter of the law, were correct. But, while Gabriel can still count himself unlucky, Santi Cazorla only has himself to blame. The FA does, however, need to get a grip of this.
Do were really want our kids following in the footsteps of a footballing thug? Someone who asks for players to be carded? Of course, Costa is not the only player to try the invisible card trick and this needs dealing with.
Players used to get carded themselves for that action - now referees appear to laugh it off. However, Costa takes things to a new level. We can not allow our kids to believe that grabbing a face, and swinging arms are acceptable.
We can not allow them to believe that confrontation to intimidate and provoke a reaction is acceptable, and we can not allow them to think that kicking out at players when they lose the ball is acceptable.
Now unless the FA act, the youngsters will believe that that is the way to play football, because, as it stands, it has been a major contributor to a Chelsea win.
Should Diego Costa face retrospective punishment from the FA? Let us know below!
