I'm in the never a pen camp and for me the issue is that none of the players in the area of where the ball lands makes a good attempt to win it / control it. So you can't really say anyone player has it and another player is making the challenge. Ings comes in with more momentum than anyone else and if anything he is committing a fowl on de ligt as much as the other way around. Its just a collision of players none of whom win the ball. If the ref had given a fowl to the rags no one would be talking about it.
If that's given against us we'd all go mad.
You've not convinced me, but good to hear some kind of explanation.
If one of ours gave that away I'd be calling them stupid.
