Bolton Wanderers are unhappy with the treatment of Chung-Yong Lee by South Korea.
Following more than a month away on international duty at the Asia Cup, the 22-year-old conceded at the weekend that he was struggling to keep up with the demands of a heavy schedule with club and country.
"After the Asia Games he's going for another friendly - just leave the lad to rest," Trotters boss Owen Coyle fumed.
"I am trying to give him rest because he's going to play a very important part for us for the rest of the season. The national team is the national team, and if this was a qualifier I could understand, but the fact is it's a friendly."
