#4. Dan Biggar (Wales)
Biggar is the epitome of players you hate until they are on your team.The way the fly-half continues to moan to referees vociferously has seemingly only got worse throughout his career. It got so bad that popular online personality and diehard Scotland fan Glove39 made a video called ‘birdman’ mocking the way in which he always raises his arms in frustration to officials.
