The Taeguk Warriors are set to take on the world champions as preparation for their 2014 World Cup qualifiers but the game could be played in Switzerland or Austria
Korea's national team are set to begin their final round qualifiers for the 2014 World Cup in June and it is understood the game would be used as preparation with a largely Europe-based squad assembling in camp.
The Taeguk Warriors, who have been drawn in Group A alongside Iran, Uzbekistan, Qatar and Lebanon, begin their fourth round campaign on June 8 in Doha.
Meanwhile, the world's number one ranked side Spain would be preparing for the 2012 European Championships to be held in Poland and Ukraine.
Reigning European champions Spain have been drawn in Group C alongside Italy, Republic of Ireland and Croatia.
According to Yonhap News, the KFA said the proposed game would be played in either Switzerland or Austria.
The last time these two nations met at senior level, Spain won 1-0 in a pre-2010 World Cup friendly.
The two sides also met at the 2002 World Cup, when Korea emerged victorious after a 5-3 penalty shootout triumph in the quarter-finals.
