Nicki Niels Bille Nielsen (born 7 February 1988) is a Danish former professional footballer who played as a forward. He has played for various Danish national youth teams, including 17 games and 8 goals for the Denmark national under-21 football team. Club career Bille Nielsen started his senior career with Danish 1st Division club BK Frem. He was promoted to the first-team in the summer 2005, and made his debut on 31 July 2005 against Fremad Amager. He signed a two-year contract with Frem in October 2005, and was on trial with English club Newcastle United in November 2005, and also had a trial with Portsmouth F.C. Though he never secured himself in the Frem starting line-up, Bille played a total 38 senior games and scored four goals for the club until August 2006. In September 2006, he moved abroad to play for Italian club Reggina Calcio in the Serie A championship, under manager Walter Mazzarri. He scored in his debut game for Reggina, a Coppa Italia game on 8 November. He got his Serie A debut on 19 November, and played seven games during the 2006–07 Serie A season without scoring any goals. He also played for Reggina's youth team, helping them advance in the 2007 Campionato Nazionale Primavera by scoring two goals in two games against A.C. Milan Primavera. Under new manager Massimo Ficcadenti, Bille had a difficult time securing a place in the starting eleven, and he underwent loan deals with Serie C1 teams A.C. Martina and A.S. Lucchese-Libertas. Both clubs went bankrupt during his stays, and according to his agent Bille did not get his wage from Reggina either. In August 2008, Bille agreed to rescind all claims of the wages owed to him, in order for his contract to be terminated a year before its expiration. He brought with him an eight match-day suspension incurred following a red card for laying his hand on the referee in a May 2008 youth team game for Lucchese. He moved back to Denmark, and trained with Danish Superliga team FC Nordsjælland in August 2008. On 18 September the Danish Football Association ruled that in order to help him re-establish his career, Bille's eight-day suspension would expire from the ninth match day of the 2008–09 Danish Superliga season even though he had not been signed by any club, making him available for selection from the start of October.
