Sweden cruised into the knockout stages of the Women's World Cup on Sunday after comfortably seeing off Thailand 5-1 to move top of Group F.
Peter Gerhardsson's side are three points ahead of tournament favorites the USA, who take on Chile later on Sunday in Paris, after a routine win, however, Sung-Ngoen scored a late consolation goal for the Thais.
Linda Sembrant and Kosovare Asllani put the Swedes two up after 19 minutes with Fridolina Rolfo rifling a long-range finish three minutes before the break.
Lina Hurtig left before the Thais, reeling from a humiliating record 13-0 defeat to the Americans in their opening match, Sung-Ngoen's restored pride through captain, drilled near post finish.
The goal sparked wild celebrations and even tears from the Thai players and coaching staff, but VAR stepped in to their mood when Natthakarn Chinwong was judged to have handled the area deep into stoppage time.
Elin Rubensson made no mistake from the spot to complete an easy win and her side qualification from the group.
Should the USA be expected to win the group the final match on Thursday if they want to win the group, due to the Americans, the goal difference advantage.
