Nice to see some Indians around here.
Let's say it is 3 pens like you just said. That gives is 6 points extra, whereas for the Muntari goal, you get 2 extra and we get 1 taken away because we'd have lost that game. That still leaves us with a good 4 point gap between us. Now stop whining.
We've had our share of valid goals not given for false-offside calls too. We can count them just as much as you would and make a case for being cheated against. These 3/4 penalties that weren't given to you get cancelled out for all the non-existent penalties your players earn by diving.
Bad decisions are bad decisions regardless of who's at the receiving end. Claiming that decisions against you hold greater value is just pathetic!
We complaining? The last time I checked, it was Milan who put up a Photoshopped pic on their website, and a pic of the Muntari goal with 'UNACCEPTABLE' written on it. Not to mention Allegri whining about it like a trained parrot.
