The Football Association is to examine comments made by Wigan boss Roberto Martinez in the wake of Monday's 3-0 defeat at Manchester City, reports BBC Sport. Martinez accused referee Stuart Attwell of giving a red card for an incident he did not see - Gary Caldwell's challenge on Carlos Tevez when the score was 0-0.

He said: "We are all human and we make mistakes but to give a decision after something you don't see that is lying.

"You are making it up. That is hard to take. It's a real injustice."

Martinez said Attwell, the youngest referee in the Premier League at 27, was wrong to send off Caldwell.

"To give a red card you have to be certain. Then you are looking at the replay it is no way it is a red card offence," he added.

"Gary said he went in really strong and got the ball. Carlos Tevez saw it, jumped off the ground, he's the one who left both feet.

"He [the referee] said he saw Gary Caldwell with both feet off the ground. That's why he gave the red card. But Gary Caldwell only went with one foot.

"The decision was a key moment in the game and until that moment we were coping really well with everything Man City had.

"I felt we were growing into the game, we had a couple of opportunities and felt that the last half an hour was going to be crucial.

"That decision was a key moment. It really cost us and the game went away from us."
