I fully agree that should have been a penalty. But you're missing the point. The pro-Liverpool brigade during and after the game made sure this was the main talking point after the game. They did the same last season with the so-called Azpilicueta foul on Luis Suarez. But Skrtel fouls Costa in the box in the FA cup, a blatant penalty and no one talks about it. He elbows a Chelsea player, silence. Gerrard pushes his head against Costa, it's Gerrard so it's no big deal. And there are countless examples like this, but I won't go on any longer.
Also, look at what the shameless Neil Ashton of the Daily Mail is leading with right now, it's incredible what's going on this season in particular. But you can choose to believe there isn't a campaign against us or at least an insane double standard.
But shouldn't it have been the main talking point - chelsea won but Liverpool were denied a clear penalty in the dying minutes that could have rescued a valuable point? There doesn't have to be a grand conspiracy, as humans we are very biased to what happens to us most recently so events that happend late on in a match tend to take on more significance than those at the start.
Naismith should probably have conceeded a penalty early on Wednesday and Ivanovic's goal in ~5th minute at Goodison (making it 0-2) should have been offside. Neither action had much press focus despite changing the dynamics of the game because we naturally focus on the latter stages and frankly most of us are drunk whilst watching anyhow!
Swansea had amazingly bad calls earlier in the season against them - red cards, offsides, penalties conceeded but not awarded etc, Monk was having fits. But there was no logical reason to call that a campaign against them.
Even if there is, you're winning despite the ******** trying to get you down - lighten up man!
