AZ Alkmaar cruised into the semi-finals of the KNVB Beker with a 5-0 win at nine-man Den Bosch on Tuesday. The visitors were already 3-0 ahead through goals from Viktor Elm, Johan Berg Gudmundsson and Adam Maher before Jelle de Bock was sent off for a foul in the area on 38 minutes. Jozy Altidore converted the resulting penalty and the home side\'s miserable night continued when Joey Brock also received his marching orders early in the second half. The game was halted briefly when snowballs were thrown at an assistant referee, but AZ were quickly back on target when the game resumed, with Maher scoring his second on the hour mark. From FIFA
