THE biggest stadium in the world is set to be built in Iraq... as a gift from Saudi Arabia's King Salman.

The 135,000-seater ground has been given the go-ahead after Iraq beat the nation 4-1 in a recent friendly match.

Prior to the game, King Salman promised to build Iraq a stadium if they ran out winners on February 28.

The match was the first full international played on home soil since the 1990 invasion of Kuwait that sparked an international embargo.

Despite being massive underdogs, the Iraqi XI ran out comprehensive winners, thanks to two goals Muhanad Ali, one from Emad Mohsin Majeed and a Saeed Awadh Al Yami own goal.

Saudi Arabia themselves have qualified for this summer's World Cup in Russia - while Iraq missed out.
