Scores match Togo Gabon
The Congo players celebrate after taking the lead in their group game
'We played a very good match tactically, ' Republic of Congo coach Claude Le Roy said.
Levy Madinda sent a shot just past the post in Gabon's completely dominant first half. He also shot just wide late in the second after weaving his way past defenders to create the opening for himself.
Between those misses, Gabon's star striker Pierre-Emerick Aubameyang missed an open goal and probably Gabon's best chance when the ball fell to him with Congo goalkeeper Christoffer Mafoumbi way out of position. Aubameyang somehow hit his low effort past the right post.
