After also being denied a penalty in last weekend’s defeat by Arsenal, Martinez said: “Shaun Maloney is not a player that looks for penalties.
“He is someone who once he gets in that one v one situation you know how effective he can be.
“He goes past his defender easily and there is no need for him to go down but I think if you look at Leon Osman’s reaction it tells you everything. If you see defending a one v one in the box and someone goes down, you go mad – and rightly so.
“Leon Osman just went away and showed a face of feeling that he got away with that incident.
”I don’t really understand what the referee saw and I am getting a bit tired of talking about these moments.“
Wigan, after narrow escapes in each of the past two seasons, appear to be heading for another relegation battle. Martinez added:
“I’m frustrated and angry. It is a moment of the season where results are starting to be very important.
“We knew we were coming to a difficult place but the way we played the first half, I thought we stopped them from having any momentum.
“We were starting to get into a good position to get a positive result and actions in both boxes cost us.
“We need to make sure we don’t rely on third parties – we don’t rely on decisions to get positive results. We will learn from it. It is not good enough just to play well.”
