Emmanuel Olisadebe (Polish pronunciation: [ɛmaˈnuɛl olisaˈdɛbɛ]; born 22 December 1978) is a former professional footballer who played as a striker.

[1] Olisadebe began his career with Jasper United in his native Nigeria, before signing with Polish top flight club Polonia Warsaw in 1997.

[3] During his time in the Polish capital he helped them secure their first championship title in 50 years in the 1999–2000 season, scoring 12 goals in the process.

[4] He made his debut ten days later, replacing Richard Hughes after 61 minutes of an eventual 1–0 Premier League defeat to Everton at Fratton Park.

[5] A week later he made his only other appearance for the club, playing the final 37 minutes of a 5–0 defeat at Birmingham City, this time in place of Vincent Péricard.

On 27 September, Olisadebe scored the opening goal for Henan in a 2–0 win over Shanghai Shenhua to regain lead in the league less than ten minutes before injuring his knee.

Initial diagnosis showed that he had torn his cruciate ligament of the left knee, and the injury could end his entire football career.

[10] Olisadebe scored Poland's first goal of their 2002 FIFA World Cup campaign in a 3–1 victory against the United States in Daejeon in the last group match.
