Manchester United boss Sir Alex Ferguson insists they deserved a penalty ahead of Arsenal in yesterday's defeat.
In regards the two penalty calls regarding Nemanja Vidic's possible handball and Gael Clichy's trip on Michael Owen, the manager felt the Reds didn't get the rub of the green.
"I think the first one is difficult for anybody to see," he asserted on MUTV. "That mere flick of the ball, a touch, you don't expect the linesman or referee to see that.
"[Owen's was a ] clear penalty kick as far as I'm concerned. He's definitely brought down but we're not going to get decisions in big games I'm afraid.
"I think we were unlucky bearing in mind I don't think Edwin van der Sar made a save. Arsenal play lovely, nice football but never looked like scoring to be honest. When we made a substitution, taking Anderson off, Ji didn't adjust to it immediately and still went to the left-hand side which freed to Ramsey to score.
"It was the only weakness in our play - giving that goal away."
