In another high-profile warm-up match behind closed doors ahead of 2021 Africa Cup of Nations qualifying next month, Morocco triumphed 3-1 over a depleted Senegal.

Cup of Nations title-holders Algeria needed less than six minutes to score the goal in the Austrian town of Sankt Veit an der Glan that sank Nigeria in a rematch of the 2019 semi-final at the flagship African competition.
Centre-back Ramy Bensebaini ventured forward for a corner and after heading the ball downward, poked it into the net.
Nigeria gave a debut to Frankfurt-born Kevin Akpoguma who, like Bensebaini, plays in the Bundesliga, and represented Germany at under-age level before switching his allegiance.
The defender is the latest of many Europe-born footballers to represent the African country where parents or grandparents come from.
Algeria last lost in October 2018 away to Benin and now move to the Netherlands for a friendly against Mexico on Tuesday.
