Angola skipper Manucho says he was disappointed not to have scored at the 2013 Africa Cup of Nations, but believes he can atone for that in future competitions.
Angola crashed out of the championship on Sunday after losing 2-1 to debutants Cape Verde and they finished bottom of Group A with just one point from a 0-0 draw with Morocco.
Former Manchester United striker Manucho hopes to return to the tournament and make an impact.
"I'm a natural goal scorer and so I'm disappointed not to have scored in this competition," admitted the lanky, dreadlocked striker who captains his country.
"But I'm still a young player and there are a lot of matches and tournaments ahead."
Manucho, who has been in superb form for Spanish La Liga club Real Valladolid this season, said the Palancas Negras (Black Antelopes) were unlucky during the tournament.
"We need to show a lot more concentration, and we failed to defend our lead against Cape Verde.
"We are all to blame," he said of the poor showing by Angola, who also made a first round exit from the 2012 tournament in Gabon/Equatorial Guinea.
