The result meant Angola finished top of Group A on five points and Algeria also went through in second place.
Mali, who beat Malawi 3-1 in Cabinda on Monday, were eliminated despite ending on the same points (four) as Algeria and with a better goal difference.
"There was no agreement with Angola," Saadane told a news conference in Luanda. "We would not accept any arranged match.
"Algeria suffered this indignity at the World Cup in 1982 when Germany and Austria played an arranged match to eliminate us. I have to emphasise the result was not arranged.
"Both teams were playing at the end not to risk anything. It was a tactical game," added Saadane.
"It wasn't a great spectacle but we fulfilled our objective," said Jose.
Algeria had the better of the exchanges and created goal chances in each half while Angola's only opportunity came in the eighth minute when Djalma cut inside the defence but failed to get any power on his shot.
Malawi pulled a second-half goal back through Russell Mwafulirwa but Mamadou Bagayoko ensured Mali's only win at the tournament five minutes from time.
