Indeed, but this 'debate' is over whether Rodriquez was intentionally looking to con the ref or not.
I can't recall many on here saying that it was a penalty. Indeed, most of us giving Rodriquez the benefit of the doubt have also indicated the ref got the decision wrong.
So, yes, if I were a Villa fan of course I'd be raging that the penalty was given. Doesn't mean I have to vilify Rodriquez at the same time.
