Chelsea manager Jose Mourinho has suggested that the Football Association 'allows retaliation' after it opted to rescind Gabriel Paulista's red card for kicking out at Diego Costa.
The Arsenal defender was sent off for committing the action during last weekend's 2-0 defeat to Chelsea.
The FA has since retrospectively punished Costa with a three-match ban for catching Laurent Koscielny's face with his swinging arm.
When asked about Gabriel's suspension being scrapped, Mourinho told reporters: "Now we know that retaliation is allowed. No problem, you can do it."
The Portuguese coach added that he feels "hurt" by Costa's ban.
