International career
Born to a German mother and Nigerian father, Sam would have been eligible to play for the Nigeria national team,[13] but decided early on to represent his country of birth.[13] He was a German youth national player, starring in Germany's under-19 and under-20 teams. On 29 May 2013, he made his senior international debut for Germany in a friendly game against Ecuador in Boca Raton, Florida.[6] On 8 May 2014, Sam was named to the 30-man provisional squad for the 2014 FIFA World Cup by German national team manager, Joachim Löw. But Sam didn't make the cut and his five internationals in 2013 became his final total with "Die Mannschaft."[14]
Style of play
Sam has been likened by observers in German football to the Dutch wingerArjen Robben of Bayern Munich,[2] due to his explosive speed and dribbling style and possibly due to his frequent deployment on the right-wing and as an outside forward,[2] cutting inside on his favoured left-foot to unleash his fierce shots,[2] which leads to him scoring spectacular long-range goals.[2] Sam is likened to a young Ryan Giggs,[2] due to his ability to dribble with the ball at top speed.[2] His comparison to Ryan Giggs and Arjen Robben is seen in the influence of the way he shoots and gets into goal-scoring situations coming in from both flanks on the football pitch.[2] He utilizes his explosive speed by running-in-behind defenders and he is often as well deployed as an outside forward and striker.[2]
