There was the possibility of a goal scoring opportunity, but there are two defenders there and others racing back (as are attackers racing forward of course). You can always say there's a possibility of an opportunity when a team is breaking at pace, very few of those end up as goals. He wasn't bearing down on goal.

We haven't appealed it because we wouldn't win as it's all so debatable but I agree with PnG's comment about Wenger having a word.

Although...if you think it was as good an opportunity as all that then surely he did need to do something and take one for the team?
