Suma was born in
Freetown, Sierra Leone. Like many African footballers, Suma grew up playing
street football in his neighbourhood. He fled his country's
civil war and moved to The Gambia in 1997. Suma was widely considered the best Sierra Leonean youth footballer while in The Gambia. In 2001, the young Suma was discovered by Sierra Leonean football agent Chernor Musa Jalloh while playing in a local football league in
Banjul, Gambia. Jalloh introduced Suma to
Mohamed Kallon, Sierra Leone's most successful footballer. Kallon asked him if he would like to play for
F.C. Kallon in the
Sierra Leone National Premier League. Suma returned to Sierra Leone for the first time in five years in 2002 and sign for top Sierra Leone National Premier League club F.C. Kallon, which is owned by Mohamed Kallon himself. In his first season in the Sierra Leonean Premier League, Suma was the second top goal-scorer. After playing in the qualifying rounds, Suma was omitted from the final squad for the
2003 African U-17 Championship in Swaziland, something he describes as the worst moment of his life. In the championship, Sierra Leone placed second, behind Cameroon, thereby qualifying for the
2003 FIFA U-17 World Championship in Finland. Fortunately for Suma, he was called back to the squad for the U-17 world championship in Finland. While the team failed to advance past the group stage of the tournament, the coach commended Suma for his energy and flair with the ball. Following this event, 12 of the 23 players failed to return to Sierra Leone and some later applied for
political asylum. Among those who
did return home was Suma. Shortly after the U-17 world championship, talent scout Chernor Musa Jalloh helped Suma move to the Swedish team
Åtvidaberg on a two-year contract from F.C. Kallon. Suma made his debut for the
senior national team on 3 September 2006 in a
2008 African Nations Cup qualifying match against
Mali in
Freetown. In December 2006, Suma was traded to
GAIS, one of Sweden's oldest teams. Suma was loaned to
FK Haugesund in the summer of 2008 for the rest of the season. In December 2012 Suma was released from his contract with
Ravan Baku. In June 2014 Suma joined
Syrianska Kerburan with fellow Sierra Leone International
Samuel Barlay, signing a new one-year contract with Syrianska Kerburan in December 2014. In July 2015, Suma's proposed move to
Kvik Halden FK fell through, before later in the same month he re-signed for
Azerbaijan Premier League side
Ravan Baku FK. ==Career statistics==
