Harry Kewell could miss Australia's crucial Group F game against Croatia after being charged by Fifa with insulting referee Markus Merk. The Liverpool winger was reported for swearing at the German official after the Socceroos' 2-0 defeat by Brazil.

Kewell has until Tuesday to respond and the verdict will be announced before the final group game on Thursday. Australia need to beat Croatia to be certain of qualifying for the knock-out stages for the first time.

Frankly, I'm encouraged that he's showing some passion for the game.
