Yoo Byung-Soo (Korean: 유병수, born 26 March 1988) is a South Korean football striker who plays for Gimpo Citizen FC. He is known as "Ronaldo of Wolmido", because of his spinless free-kick that resembles that of Cristiano Ronaldo's. (Wolmido is a small park in Incheon city, where he started his professional career).
Yoo entered Dunchun Middle School, scoring at least one goal in nearly every match he played in. Then he entered Unnam High School, winning the top scorer award in a couple of national competitions. After graduating from high school, he decided to enter Hong-Ik University, winning the top assists award in National University Competition. Thus having grabbed the attention of many scouts, he joined K-League side Incheon United.
In the pre-season, Incheon sold its franchise star striker Bang Seung-Hwan to Jeju United. This transfer worried many Incheon fans as they had already sold another striker Dženan Radončić to Seongnam Ilhwa. However, Incheon's newly appointed manager Ilija Petković said that Yoo Byung-Soo could be the replacement, and he can develop into a new franchise star for Incheon.
On 3 March 2009, Yoo scored in his senior debut match against Busan I'Park. In his debut season in K-League, he was widely regarded as one of the best candidates for the Rookie of the Season award but eventually Gangwon FC's forward Kim Young-Hoo grabbed the award. In November 2009, he was linked with Premier League side Bolton Wanderers.
In July 2011, Yoo signed a new contract with the Asian club of the century, Al Hilal in Saudi Arabia, running until 2014. He scored a total of 16 goals while playing 44 league matches in two seasons for the Riyadh-based team.
Gimpo Citizen FC
In 2017, Yoo joined Gimpo Citizen FC for public service work.
