Encroachment when a penalty is being taken annoys me. Some players are yards inside the box before the ball is kicked yet refs and both linesmen and the 4th official and VAR don't seem to notice or care.
Alex Munro, dirty gas bastard. Broke his leg at AG in Glos Cup 1968 after colliding with the pitch side seats in front of the old enclosure after sliding in on Chris Crowe trying to clatter him. Karma.
