The two countries face each other in the last eight for the fifth time in a row, and Ghotbi believes it will be the highlight of the tournament so far.
"Iran-South Korea is a fixture etched in stone in the Asian Cup. It seems like every Asian Cup we meet and I believe it will be a classic between two of the best teams in Asia," he said.
"I expect a fantastic match and I hope all of Asia will tune in and the world will watch Asian football at its best."
His opposite number Cho Kwang-Rae was not nearly as optimistic, however, warning fans should expect a cynical Iran. "They may start by committing a lot of fouls. Fans don't like to watch this," Cho said.
