Frustrated Jose Mourinho's self-imposed gag over Diego Costa controversy

Chelsea chief Jose Mourinho admitted he had to gag himself or risk a ban after Diego Costa was suspended by the Football Association.

The striker was handed a three-match ban for violent conduct following his clash with Arsenal’s Laurent Koscielny on Saturday.

Costa had denied an FA charge over the incident, not seen by referee Mike Dean, in which he appeared to raise his hands to Gunners defender Koscielny in the 2-0 win. On Tuesday Arsenal defender Gabriel won an appeal against his red card for confronting Costa after the initial incident.
