But he didn't miss it because he gave the free kick. Mind you, it's Andre so I'm not surprised reaction is muted. Can't help thinking if it had been Lee Mason or Kevin Friend, there would have been greater feeling expressed. It's perfectly reasonable to look for reasons why a referee may have missed something but that doesn't mean the error should be ignored in the first place. Nor should simply mentioning possible bad angles or restricted view, without visual evidence that was the case, be used to exonerate a referee. If someone can show Marriner's view wasn't the best, fair enough. Otherwise, it was badly misjudged by Marriner and missed by the other officials.
That incident aside, I didn't feel AM's foul detection overall was up to his usual standard. However, he is good at talking to players and generally seems well respected.
