Wigan Athletic boss Roberto Martinez won't stop speaking out.

Martinez is refusing to be silenced as he considers an appeal against his £10,000 FA fine.

The Spaniard was punished this week after being found guilty of misconduct. He had suggested referee Michael Oliver had been biased against his side during a 4-0 defeat at Manchester United.

The Latics chief said: "I think it is important after a match you can be honest and have a pure assessment of the game. That is what I did.

"It was based on the stats and what happened in the game.

"I would never question the integrity of the referee or question if the referee was biased towards a decision. That was never the case.

"I was talking about the experience that we at Wigan Athletic have had going away from home and ­unfortunately the calls we have had of late.

"We are waiting if we can appeal the decision because it is something I don't agree with."
