Roberto Martinez: "Remember Callum McManaman was making his full debut in the Premier League and, as a young man, you know you are going to give your life for everything.
"I haven't seen it but I believe he gets the ball and then it's a bad challenge.
"No-one wants to see that but I guarantee that is just a striker trying to win the ball over-enthusiastically because he is making his (full league) debut.
"What you need to look at in those incidents is if there is intention, a nastiness about the tackle. We are not a nasty team.
"He has not a nasty bone and is not bad-intentioned. The referee was in a perfect position, he is looking at the incident, where the ball is and where the ball is hitting.
"When you get the ball and then there is a follow-up it is very difficult for a panel to punish that."
