Newcastle United boss Alan Pardew was of the belief that his team were on the wrong side of some questionable referee decisions on Sunday.
The Magpies went down 1-0 to Arsenal at St James' Park when Theo Walcott's set-piece was headed home by Olivier Giroud in the 65th minute but Pardew feels there should have been a free-kick paid to his side moments earlier.
"There was definitely a foul before then on (Vurnon) Anita, without a shadow of a doubt; there was a foul on (Moussa) Sissoko that he (referee Lee Probert) didn't give," said Pardew.
"In terms of the breaks of the decisions, I don't want to say the referee had a poor game, but sometimes he sees those calls and they go your way, sometimes they don't.
"Against Stoke (5-1 win on Boxing Day when two Potters players were sent off), we had all the calls go our way and today, perhaps we were on the other side of it.
"It's just frustrating, a little bit, that we have not got something on the scoreboard in terms of a point, no more than that.
"One set-play where we didn't defend well has cost us and we have been good at them all year."
