McGeady vs Eduardo

"Is it a dive? Never in a million years. A dive is when you try to influence the referee, you throw your arms up and so on."The quote above is what Tony Mowbray said following Aidan McGeady's yellow card for diving yesterday. I have a degree of sympathy with McGeady, we have seen in the past few days just how randomly the media can react to extremely similar incidents. After all what is a dive?
