Time wasting.
Grrr! It makes my blood boil. It deprives the paying spectator of the thing they actually came to see - Football itself.
Goalkeepers constantly positioning and re-positioning the ball for goal kicks. Book 'em.
Rolling back onto the pitch to feign injury. Book 'em.
Walking right across the pitch when being substituted. Book 'em.
Going over to the ref to shake his hand when being substituted. WTF! Book 'em.
Injured players lying on the ground. Play on around them.
Stamp out time-wasting out. It's anti-football.
I haven't got a #3.
