Wigan Athletic manager Roberto Martinez could be charged by the Football Association following comments made about referee Stuart Atwell after Monday night's defeat at Manchester City.
Roberto Martinez speaks to ESPN
Martinez effectively accused the official of lying about the red card handed out to central defender Gary Caldwell. The Latics' boss believes Atwell did not actually see the tackle but still chose to dismiss the player signed from Celtic in the January transfer window.
It seems certain that the FA will now look at Martinez's comments.
Following the loss, the Spanish coach 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. 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.
"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."
