Ratface and stirling to name a few made a living out of these type of penalty awards whist playing for the RS, but suppose that doesn't count thoughBiggest problem for the FA would be proving Lewin intentionally dived. He doesn't over exaggerate going down, he falls in the direction he was pushed, he was running at pace on a wet pitch.
Now I bet the FA and their panel would be dying to pull this in and find Lewin guilty because it was against the RS, but could you imagine what it would be like if they did.
