4) Lee Chung-yong (Bolton & Crsytal Palace)
The winger spent six seasons with Bolton, three in the Premier League and another three in the Championship. He was a consistent performer before he joined Crystal Palace in the 2015 January transfer window.
Lee never really established himself at Selhurst Park and he was released in 2018, having been used pretty sparingly. He then joined German club Bochum before moving back to South Korea a couple of years later.
