I've had a few handballs this season.
Two somewhat amusing incidents;
Striker gets the ball just outside the box in a central area. Defender flies in, takes him out. I spy with my little eye, his strike partner clean through on the inside edge of the box. The ball goes to him. I shout "ADVANTAGE!"
He flicks the ball in the air and catches it. I blow the whistle and give a freekick against him. He tried to argue that there was a freekick, and I conceded, that yes, it was a foul, but you were wide open, clean through on goal and for whatever reason you picked the bloody ball up. Not my fault you've thrown the advantage away there. Even the defending team were taking the piss out of him, and even his own team were a bit miffed and (fortunately) happy to recognise it was a good advantage call... -_-
Second one...
Player tries a cross-field pass, the receiver looks up, realises it is far too high and going out of play, and so he jumps up and catches the ball. Blow the whistle, free-kick, no caution. Both teams took the piss out of him for that one.
There's been a few claims for handball in the box on the goal line, which I've missed from bodies getting in the way. Some of them are my own fault from lack of match sharpness on positioning. Some of them, there's no chance I would see them without getting in the way of play. Can't get them all I guess.
