There was plenty of controversy after Arsenal fell to Chelsea on the power of a first-half red card to Gabriel Paulista, a punishment earned by the provocation of Diego Costa.

What he doesn’t understand is why the Brazilian-born Spanish forward is allowed to verbally and physically provoke opponents in an unsporting fashion... and he wants an investigation into it.
From the BBC:“He [Costa] will do the same again next week and the week after that and he always gets away with it,” said Wenger.
When asked if the FA should take retrospective action, Wenger added: “That is the least they could do.
“Costa can do what he wants and yet he stays on and everyone who responds to him has to be sent off. He hits Koscielny in the face yet he gets away with it.”
Fair enough, or sour grapes? I vote fair enough.
