The midfielder who can also play as a striker started playing football at TuS Mettenhof. After that, he played at Kilia Kiel. In the summer of 2002, he signed for the city rivals of Kilia Kiel, Holstein Kiel.
At the beginning of the 2004–05 season, he moved on to the Hamburger SV youth system, and in 2006, he was promoted to the second team. In the 2007–08 season, he became part of the professional pool of Hamburg.
On 20 December 2007, he made his debut in the Bundesliga against VfB Stuttgart when he came on for David Jarolím. He joined 1. FC Kaiserslautern on loan for the 2008–09 season and was loaned for another season on 1 July 2009.
Sam then moved to Bayer 04 Leverkusen in 2010 as he signed a five-year deal. He started off the season well and on 8 November 2010, he played against his former club 1. FC Kaiserslautern. Down 1–0, he started the comeback when he smashed a driven shot into the net. Patrick Helmes then completed the comeback as he made it 2–1. The day belonged to Sam as he smashed home a first time volley almost 25 meters out and stunned the entire stadium and made a name for himself that day. On 17 February 2011, he scored a double in Bayer's UEFA Europa League match against Metallist Kharkiv, with both goals coming in added time.
Born to a Nigerian father, Sam would have been eligible to play for the Nigeria national team but decided early on to represent his country of birth. He was a German youth national player, starring in Germany's under-19 and under-20 teams. On 29 May 2013, Sam made his senior international debut for Germany in a friendly game against Ecuador in Boca Raton, Florida.
