The Angolan team, coached by Portuguese Pedro Gonçalves, was losing to favorite Algeria since the 18th minute, when striker Baghdad Bounedjah, from Al-Saad, leader of the Qatar championship, opened the scoring.
However, Angola never became disorganized and resisted the greatest offensive harassment from the Algerian team, ending up being awarded a shot in the opposite area that deserved a penalty, converted by striker Mabubulu, who plays for Al-Ittihad, the reigning champions of Saudi Arabia, won last season under the technical command of Portuguese Nuno Espírito Santo.
Given Algeria's clear favoritism, due to its value and its history (twice winning the CAN), this draw for Angola was an excellent result, which opens up good prospects for a possible qualification for the next phase.
The Angolan team remains with one point, like Algeria, at the top of group D, which also includes the teams from Mauritania and Burkina Faso, who will face each other on Tuesday.
Angola's feat follows those that Mozambique and Cape Verde had already achieved on Sunday, with the former imposing a 2-2 draw against super-favorite Egypt, the competition's record holder with seven titles, and the latter beating Ghana, four-time champions of the competition, 2-1.
In other games this Monday, Senegal, the current title holder, had no difficulty in beating the fragile Gambia team, 3-0, in a Group C game, with a goal from Pape Gueye, midfielder for French side Marseille, in the fourth minute, and an encore from Metz midfielder Lamine Câmara, in the 52nd and 86th minutes.
In the other match in Group C, the Cameroon team did not go beyond a 1-1 draw against their counterparts from the Republic of Guinea, who came to have an advantage.
Mohamed Bayo opened the scoring after just 10 minutes, but the 'indomitable lions' tied in the second half, at 51, through Frank Magri, forward from Toulouse, Benfica's opponent in the 'play-off' to reach the round of 16 of the Europa League.
