#4 Worst: Brian Idowu
Idowu's laziness and unprofessional footballing approach were one of the main reasons for Nigeria's abysmal first-half display.
Their defence was flat for the most part of the opening 45 minutes. Iceland's crossing and attempted long balls and diagonals proved to be a headache for their opponent's defence.
Idowu was often beaten and battered by Gislason, Saevarsson and Gylfi Sigurdsson. He couldn't cope with the dynamism posed by them, as they aimed to get in behind the defence through a couple of give-and-go's.
Also to add, he added almost nothing going forward. The Nigerian forwards had to spread out due to the lack of supply from the left flank. He also picked up a yellow card for a poor challenge.
No wonder he was substituted after the break.
