Iceland holds a commanding lead in UEFA Nations League Group C4 with 8 points from four matches, a +6 goal difference, and an unbeaten record of two wins and two draws. The other sides trail significantly: Estonia sits second on 6 points with three draws, while Bulgaria and Luxembourg have just 4 and 3 points respectively after mixed results. Iceland’s remaining fixtures against Bulgaria and Luxembourg provide clear opportunities to extend their advantage before the November matchdays conclude. Estonia’s draw-heavy form limits their upside despite a solid defensive record, and the lower teams face steep deficits that make recovery unlikely. This performance gap and fixture schedule underpin the market’s strong consensus around Iceland as group winner.
