I hate that people say it was a pen, but Gerrard would have been sent off. One changed moment at any point during the game changes EVERYTHING. From the moment we would have taken that pen, the ball would have gone to the center line, or out of bounds somewhere, or in the keepers hands, or played on from there, in a different spot from where arsenal ended up pulling it out. Every moment in the game from that point on would have been completely different in that moment in time. It changes everything, and that Gerrard tackle never would have happened.
Besides, webb was so inconsistent with his yellow cards. Podolski probably had the worst challenge in the game and didn't get one. He could have had 3 or 4 yellows on his own with all his ridiculous challenges, not to mention when Monreal pulled back Sterling which is usually bookable. webb was just all over the place yesterday.
