I give you Charlton at home. Yes it was a pen, but no one other than ref saw it. Just very rare that we get the rub.
No it's way worse than that. Sibbick did a perfect tackle, ref blew up. The number of dives they've got away with is laughable.
If you get a 50/50 challenge it seems that you will "Win" a foul if you go down. It really annoys me when refs are blowing for 50/50s.
