Odds: South Korea $1.65, draw $3.35, Iraq $6   (Ladbrokes)

FIVE TO WATCH

Younis Mahmoud  (Iraq)

Ageless striker and inspirational captain of a young but immensely promising Iraqi side. Skippered Iraq to 2007 title and would love to repeat.

Son Heung-min (South Korea )

Supremely talented attacking midfielder and a player of real quality. Scored both extra time goals to take the Taeguk Warriors to the semi-finals in the 2-0 win over Uzbekistan.

Yaser Kasim (Iraq)

Hard-working youngster  who is a crucial part of Iraq's midfield, Kasim scored the winning goal in the group game against Jordan which proved crucial to their qualifying for the last eight.

Kim Jin-hyeon (South Korea) 

Seems to have established himself as South Korea's No. 1 having played in three of the four games so far. Had a terrific match against Australia, and will be a critical figure if this match goes to penalties.

Ki Sung-yueng(South Korea)

The Swansea midfielder is the captain and steady point of the South Korea midfield and a critical presence as the Koreans look to retain possession and recycle the ball.

IN THE DUGOUT

Radhi Shenaishil (Iraq)

Former national team defender is in his second spell in charge of the Lions of Mesopotamia. Has also taken charge of the under-23 team.

Uli Stielike (South Korea)

Hard-headed German who only took the reins at South Korea after their disappointing World Cup but has worked hard to get them back on track in double quick time.

AND A BIT OF POLITICS

Korea Gas Corporation has put itself into Iraq for the long haul, announcing last year  it was investing  $4.9billion in the country's Zubair oil field project. Other shareholders include  US company Occidental Petroleum.
