Its not just an attacking ploy though. It also slows the game down, making it a more scrappy stop start affair, and so making it more difficult for 'footballing' sides to get into a rhythm of play.
It's a shame really as they have a few good footballers in the side.
Hannibal, as much of a twat as he is, is a good player. Chong, Bellingham and Khadra are good footballers too.
