The Democratic Republic of Congo became the latest underdogs to roar at the World Cup on Saturday, battling into the knockout rounds for the first time as Iran’s rollercoaster campaign ended in elimination. A chaotic finale to the tournament’s expanded group phase saw Austria and Algeria fill the final two berths in the last 32 late on Saturday after battling to an extraordinary 3-3 draw in Group J — a result that dashed Iran’s hopes of advancing from their group. A win for either Austria or Algeria would have allowed Iran to squeeze into the last 32, and it looked as if the Asian side would advance when Riyadh Mahrez scored in the third minute of stoppage time to put the Algerians into a 3-2 lead.
