Shin Tae-yong hopes his side's first World Cup opponents will be hampered by not being able to distinguish between several of his players
South Korea hope to have kept their tactics against Sweden a surprise by swapping shirt numbers in recent training sessions and matches, coach Shin Tae-yong has said.
Shin's men kick off their World Cup campaign in Nizhny Novgorod on Monday in what has been described as a must-win match, with Mexico and Germany the other opponents in Group F.
Players have been seen wearing different numbers during preparations for the finals in Russia and Shin says it was a deliberate ploy to confuse any Sweden scouts ahead of the match.
