South Korea opened their Group B campaign with a goalless draw against Palestine, while Oman suffered a 1-0 defeat to Iraq, with Aymen Hussein netting the only goal of the contest.
Match preview
Oman have never competed in the finals of a World Cup, but they enjoyed their best qualification campaign for the 2022 competition, winning 10 of their 18 matches.
Jaroslav Silhavy's side finished top of Group D in the second round, picking up 13 points from their six matches courtesy of a record of four wins, one draw and one defeat.
However, Oman could not make a winning start to Group B, with Aymen Hussein's goal seeing them suffer a 1-0 defeat to Iraq, so there is pressure on the home side to pick up a positive result in this match.
Oman have tackled South Korea on six previous occasions, losing five of those matches, with their only victory coming in the Asian Cup back in October 2003.
South Korea have competed in the finals of 11 World Cups, including the last six, with their best-ever finish coming in 2002, when they secured fourth.
In 2022, the national side reached the round of 16, losing 4-1 to Brazil, and they will be expecting to be present in the finals of the 2026 competition.
Hong Myung-bo's side were held to a goalless draw by Palestine in their first match in Group B last time out, but they had been on a three-game winning run ahead of that clash, including a 7-0 success over Singapore.
South Korea finished top of Group C in the second round of qualification, claiming 16 points from their six matches courtesy of a record of five wins and one draw.
Myung-bo, who played 137 times for South Korea during his playing career, is in charge of the national team for the second time, having previously been at the helm between 2013 and 2014.
