Marriner was awful yesterday, properly terrible display.
I have no real arguments with the Kolo Toure or Zabaleta bookings, both were worthy of cards. However in Kolo's case the foul came out of frustration that he didn't get a freekick for yet another foul against him by Ba, who spent the entire game fouling the City centre halves without being pulled up for it.
Rodwell's booking was a joke. He was warned earlier for cleanly winning the ball in a tackle and then was booked for failing to connect with Ivanovic who was throwing himself to the floor.
The penalty I don't have much issues with, I felt it was pretty clear and we'd have been screaming for it if it was the other way round. So, no, no issue with the penalty itself. What I do have an issue with is that the play reached that point and allowed Hart to bring Ba down. Ba was all over Kolo Toure when the ball was lumped over his head, something which seems to have been ignored by virtually eveyone in the media. He had his arms over his shoulders as they turned to chase the ball, and he was clearly impeding Toure, which allowed him to get past and into the box, yet another Marriner error.
The final statistics, if you believe the BBC Website, were that possession yesterday finished at 50% each. Now, given we had the same amount of the ball as Chelsea, and we were the ones who clearly played far better, creating more chances and winning the game, you'd be forgiven for thinking, at worse, the foul count would have been pretty even. No, Chelsea committed just 5 fouls during the 90 minutes compared with City's 19! Sky had similar stats, with Chelsea shading possession 53% to 47% but City "winning" the fouls count hands down by 20 fouls to 5!
