Mauritania boss Amir Abdou feels his players will not be downhearted by the “injustice” of their opening Africa Cup of Nations defeat when they come up against Angola.

The Lions of Chinguetti lost 1-0 to Burkina Faso in heartbreaking fashion as Bertrand Traore’s penalty in the sixth minute of second-half stoppage-time condemned them to a Group D defeat.

“It was a bit of injustice to us as the boys gave everything, they followed instructions,” head coach Abdou said ahead of Mauritania’s second group game in Bouake.

“Our performance dropped in the second half because of the heat and there was a lot of suffering.

“We are not going to slumber in sorrow. We need to move on from this and prepare ourselves for the next game, which is against Angola.”

Angola began their AFCON campaign with a 1-1 draw against two-time winners Algeria, extending their unbeaten run to six games.

Head coach Pedro Goncalves said: “This team started slowly but we managed to find some spaces and came back into the game in the second half, which the team did better.

“The work isn’t done. The team showed that mentally they are up there so we will continue to build on this in our next matches.”

Mauritania, who are without a win in five games, could be without Aboubakar Kamara.

The former Fulham striker, who now plays for Al Jazira in the UAE Pro League, had to be replaced after 28 minutes against Burkina Faso after sustaining an injury.

Angola could hand a start to Mabululu after the striker came off the bench to score against Algeria.
