Vassilis Spanoulis, Greek basketball player
Vassilis "Billy" Spanoulis (Greek: Βασίλης Σπανούλης; born 7 August 1982) is a Greek former professional basketball player who spent the majority of his career playing for Greek Basket League and EuroLeague club Olympiacos. A 6 ft 4 in (193 cm) tall combo guard, he is nicknamed Kill Bill, V-Span, and MVP ("Most Vassilis Player"). Spanoulis was named the Balkan Athlete of the Year in 2009, the All-Europe Player of the Year in 2012 and 2013, the Vatican's World Athlete of the Year (Giuseppe Sciacca Award) in 2013 and the EuroLeague MVP the same year. He has earned a record eight All-EuroLeague Team selections and was voted the EuroLeague's 2010–2020 Player of the Decade. He is also the EuroLeague's all-time career leader in total points scored.Spanoulis first played pro club basketball with Gymnastikos S. Larissas, and enjoyed a highly successful career start. His skill-set earned him a transfer to Athens and Maroussi, where he won the Greek Basket League's Best Young Player award in 2003. Following an impressive 2004–05 season, during which he helped lead Maroussi to the Greek Basket League's finals and the EuroCup quarterfinals, he moved to Panathinaikos, where he became one of European basketball's major stars. In the 2005–06 EuroLeague season, Spanoulis made his debut in impressive fashion, earning his first All-EuroLeague Team selection as a rookie in the competition. After a stint in the NBA with the Houston Rockets during the 2006–07 season, he returned to Panathinaikos and helped lead them to a EuroLeague title in 2009, being voted the EuroLeague Final Four MVP in the process.Spanoulis' transfer to Olympiacos from Panathinaikos in the summer of 2010 marked a new step in his career, given Olympiacos' feisty rivalry with Panathinaikos. Within a young and rebuilding Olympiacos team, Spanoulis not only led the club to a EuroLeague title run in 2012, but he also went on to lead the team to a historical EuroLeague championship repeat in 2013. In the process, he gained another two EuroLeague Final Four MVP awards, thus joining Toni Kukoč as the only players in the history of European basketball to achieve that distinction on three occasions. Under his leadership, Olympiacos reached another two EuroLeague Finals, in 2015 and 2017.

In 2017, European basketball historian Vladimir Stanković, named Spanoulis the "Most Clutch Player in EuroLeague History". In 2020, Spanoulis was named the "Best EuroLeague Player of The 2010s Decade" by the readers of the website Eurohoops.net.Spanoulis also played an instrumental role on the senior men's Greek national team's 2005 EuroBasket gold medal team. Most importantly, he was one of the main stars of Greece's 2006 FIBA World Cup silver medal team, scoring 22 points in the memorable victory over Team USA (101–95), in the tournament's semifinals. It was however, Greece's bronze medal at the 2009 EuroBasket, that emphasized Spanoulis' leadership within an injury-plagued Greek national team, and consequently earned him an All-EuroBasket Team honor.
