It was the same act. It was the same offence as Wilshere's as in he stuck his middle finger up, two in fact, waved them about for a couple of seconds, whereas Wilshere flipped his finger for the same amount of time. The panel should have come to an unanimous decision and he should of been banned.
Like you, I'm not bothered either way, but there has to be consistency in the punishments. Essentially the message the panel have sent out is that players can now celebrate by flashing their middle fingers in the air for a couple of seconds. That's what infuriates fans. I've got no problem with it, let's get wild and let players swear like idiots during celebrations but you either let them all off if the ref hasn't seen it or punish them all in my opinion. How the panel couldn't come to an unanimous decision is beyond me.
