I refer the honourable gentleman to my previous post.  

There was an incident involving Gordon and initially, Gallagher felt it should have been a penalty following a tangle with Dejan Kulusevski. However, the former official went back on his initial decision, he said: "I have to hold my hand up here because when I saw this first of all I thought penalty. A lot of the times I think go with your gut reaction.  "When I look at it I think, my mantra somebody pointed out on Sunday when I pointed out was 'look, the guy is already there what can he do. He can't make himself invisible. So I think they have clashed and I think actually the referee has got it right."
