South Korea rallied from a goal down to defeat the Czech Republic 2-1 and make a winning start to their World Cup Group A campaign, much to the delight ‌of their fans and the sizeable local Mexican support they enjoyed in a festive Guadalajara on Thursday.The Koreans joined Mexico on three points at the top of the pool after the co-hosts defeated nine-man South Africa 2-0 in the tournament opener in Mexico City.Ladislav Krejci put the Czechs ahead with a fine header as the European side dominated in the air, but ⁠Hwang In-beom equalised shortly afterwards and turned provider for substitute Oh Hyeon-gyu’s winner.Oh had come on for ‌the misfiring Son Heung-min, who had five chances in the first half alone but endured an off-day in front of goal and is still two goals shy of ‌the all-time scoring record for the side, failing to add to his 56 strikes. ⁠South Korea next face ⁠Mexico on June 18 and the Czechs travel to Atlanta to meet South Africa on the same day.Hwang In-beom (right) dinks in a clever equaliser for South Korea in the 67th minute.
