Hearts of Oak striker Mahatma Otoo says his international career has been made complete after receiving a debut Black Stars call-up. Otoo has been invited for the 2014 FIFA World Cup qualifier against Sudan on March 24 at the Baba Yara Stadium in Kumasi. He has represented the country at the U17 and U20 levels and was captain of the national U23 team that won a historic All Africa Games gold medal in Maputo two years ago. Otoo is delighted at the call-up and has praised the Black Stars technical team for the opportunity given him. "I would like to thank the technical team and the coach for this opportunity," said Otoo in an interview with Joy Sports "I have played for a couple of junior national teams and rising through the ranks to this stage is great for me. "I have been trying my best at club level and to maintain my form for sometime has not been easy and I think the technical team has realized my potentials and the best time to try me." Otoo has been in fine form for his club Hearts of Oak this season, scoring 8 goals in the Ghana premier league.
