Angola skipper Manucho says he is disappointed at exiting the Africa Cup of Nations without scoring a single goal.
But the former Manchester United striker believes he can atone for that in future competitions.
The Palancas Negras crashed out of the championship on Sunday after losing 2-1 to debutants Cape Verde.
The 2010 hosts finished bottom of Group A with just one point from a 0-0 draw with Morocco's Atlas Lions.
Their only goal of the competition was actually an own goal by Cape Verde's Neves in Sunday's clash.
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.
"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 club Real Valladolid this season, said the Palancas Negras 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.
