Nana Otto Addo (born 9 June 1975) is a German-born Ghanaian football manager and former player. He was recently the manager of the Ghana national football team, and works as a talent coach for Borussia Dortmund. Early life Addo was born on 9 June 1975 in Hamburg, West Germany to Ghanaian parents. Club career VfL 93 Hamburg Addo started his career in 1991 in Hamburg playing for Hamburger SV. In 1993 he left Bramfelder SV after playing there for a year to join fellow Hamburg side VfL 93 Hamburg in 1993 where he played 80 league matches and scored 4 goals from 1993 to 1996. Hannover 96 Addo moved to Hannover 96 in the Regionalliga Nord (third German league) in 1996. He made a big impression in a squad that featured stars-to-be Gerald Asamoah and Fabian Ernst. That team ripped through the season scoring more than 100 goals but succumbed to Energie Cottbus in the 1997 promotion playoffs. In 1998, Hannover finally promoted to the 2. Bundesliga. In his first season, he scored seven goals in 30 games and was acknowledged as one of the elite players of the league. Borussia Dortmund Addo transferred to Borussia Dortmund in 1999 and played more than 75 times for the team, becoming Bundesliga champion in 2002. However, he was also hampered by great injury troubles, as he tore his cruciate ligaments three times in this time, the first coming after a German Cup match against SC Freiburg on 15 July 2001. The player had an MRI scan which showed he had torn knee ligaments and underwent surgery on his right knee on 22 July at the Vail, Colorado clinic of world-renowned knee specialist surgeon Dr. Richard Steadman. He healed completely after that, and came back to play the 2002 UEFA Cup Final for Dortmund against Feyenoord Rotterdam on 8 May 2002, which Dortmund lost 3–2 at the Feijenoord Stadion in Rotterdam. On 7 September 2002, Addo tore right knee ligaments for the second time, in a 2004 African Cup of Nations qualifier versus Uganda in Kampala. On 24 September 2003, Addo's career was under threat after he re-injured his troublesome right knee for the third time in Dortmund's 2–1 UEFA Cup victory over Austria Wien. He started the match, but was replaced after just 38 minutes. After sitting out the whole of 2004, Addo returned to action as a substitute in Dortmund's 1–1
