Gabon opened its African Cup of Nations campaign with a 2-0 win over Niger on Monday in Group C.
Pierre-Emerick Aubameyang sent a far-post header into the net in the 30th minute from a deep cross by Stephane Nguema as co-host Gabon controlled play throughout the first half.
Nguema swept a loose ball home for the second just before halftime after Aubameyang’s close-range header was saved.
Niger was starved of possession and completely outplayed on its African Cup debut at a packed and rowdy Stade de l’Amitie.
Gabon went to the top of the group ahead of Tunisia who edged out a wasteful Morocco 2-1 in their derby.
Saber Khalifa’s faint touch on Khaled Korbi’s 34th-minute free kick helped guide the ball home and send Tunisia into a surprise lead over its North African rival. Substitute Youssef Msakni made it 2-0 with a fine solo run and finish in the 76th.
Houssine Kharja scored a contentious late goal for Morocco to set up a nervous finish.
