Group D
All sorts of outcomes are possible here with Croatia, on six points, through but the other three teams still in the hunt.
Croatia will top the group if they beat or draw with Iceland.
Nigeria, on three points, will secure their spot in the last 16 with a victory over Argentina, who sit bottom of the group on one point behind Iceland on goal difference.
A draw may also be enough for Nigeria even if Iceland beat Croatia, depending on goal difference.
To go through, Argentina need to beat Nigeria while hoping Iceland lose to or draw with Croatia. If Iceland and Argentina both win, to move to four points, they will be split by goal difference.
Iceland must win to have any chance but also need the other results to go their way....
