It really is considering how many penalties have been awarded to players parting with the ball to gain advantage in the area or to pass to a team mate, even if the pass went astray.
Exactly. Could be a pussy out by the referee because of what has been said by Inter people lately about penalty decisions, but even Ranieri admitted it should have been given IIRC.
On one hand, it's annoying because Inter were playing the victim for most of the week to try to get a call their way. On the other, not having the penalty awarded (and the 'keeper sent off) denies them another chance to complain and gives them an excuse for their defeat.
Oh, apparently Marchisio is absolutely beloved in Torino (according to the aforementioned guests from that city). Then again, three of the four are women, so, can't really take their word for much!
