Wigan manager Roberto Martinez weighing up appeal over FA charge relating to Manchester United comments Wigan manager Roberto Martinez looks set to appeal a Football Association charge for comments he made after the Barclays Premier League game against Manchester United on September 15. Wigan lost 4-0 at Old Trafford during which the Latics boss was unhappy about a penalty awarded to the hosts, as well as a Danny Welbeck challenge on Franco di Santo which he felt warranted a red card. Martinez has until 4pm today to contest the charge against him for comments he believes were "rational." "I have to look into it because I never questioned the integrity of the referee," Martinez said. I don't know really which comments are the ones for the charge but I'll look into it and we'll take it from there. The charge must be based in certain quotes and I think it will be a good opportunity to explain myself. I need to find out first what are the quotes or the lines that have been charged on. I can understand that sometimes things can be taken out of context. I was rational, it wasn't an emotional burst. I think it was a very rational comment that I would like to explain. I am sure they are not going to charge for the sake of it. There must be a reason behind it and I need to see their point and have time then to express mine. I can remember my points in the press conference and I can remember the analysis of the game and I have huge respect for the referee Michael Oliver and would never question his integrity. But it is true we were on the wrong end of two big decisions and that's something you have to comment on at the end of a game. Martinez said after the defeat at Old Trafford: "I have come to United three times before today and for whatever reason we don't seem to be measured in the same manner as the team at home. Martinez also described Welbeck's challenge as "completely reckless," adding: "It is a red card, for a Wigan player, Manchester United, everyone." The comments prompted the FA to charge the former Spaniard with a statement adding: "The charge is in relation to an alleged breach of FA Rule E3 concerning media comments which implied that the match referee and/or match officials in general are motivated by bias and/or brought the game into disrepute."
