(FIFA World Cup 2018) : South Korean Coach Made Players Swap Shirts To Fool Opponents.

On Sunday at a press conference in Nizhny Novgorod, Russia, South Korea football coach Shin Tae-yong told reporters that he made players switch shirts during recent friendlies to "confuse" opponents.

“All coaches probably feel their opponents are always spying on them.

“I think it’s perfectly natural that we all try to get as much information on each other as we can.”

Tottenham striker Son Heung-min and captain Ki Sung-yeung were the only players who wore their usual shirts against Bolivia and Senegal earlier this month, Tae-young added.
