Son Heung-min scored twice as Tottenham edged past a team of the best players from South Korea's top flight to secure a 4-3 friendly win.
Dejan Kulusevski opened the scoring after 29 minutes before South Korea and Spurs captain Son made his mark on his homecoming in Seoul.
He curled an effort into the top corner after 38 minutes and slotted home a Kulusevski assist to give his side a 3-0 lead by the break.
But Team K League pulled two back in the second half after replacing their entire team at the break with Stanislav Iljutcenko netting twice within five minutes of the restart.
