South Korea have lacked attacking flair and struggled to break teams down in 2018 World Cup qualifying but coach Uli Stielike says it is too soon to bring exciting Barcelona youngsters Lee Seung-woo and Paik Seung-ho into the full national side.

Lee and Paik, who have come through the Catalan club’s famous La Masia academy and are regarded as two of the most promising talents in Spanish football, have impressed at the ongoing Under-20 World Cup in South Korea.

Both players scored in each of the victories over Guinea (3-0) and Argentina (2-1) to help the Koreans reach the last 16, where they will face Portugal on Tuesday.

But while the wing wizardry of Lee and Paik’s range of defence-splitting passes have lit up the U-20 World Cup, Stielike said senior international football was an entirely different game.

South Korea have appeared at every World Cup finals since Mexico 1986 but their hopes of grabbing one of the two automatic berths from Group A of Asian qualifying for next year’s finals in Russia hang in the balance.

They trail group leaders Iran by four points and lead Uzbekistan by just one, and, after playing Qatar in Doha on June 13, must face both teams in their final two matches.
