Senegal have become the first country to qualify for the 2022 Africa Cup of Nations in Cameroon after a 1-0 victory over Guinea-Bissau on Sunday.
Sadio Mane separated both teams at the Estadio 24 de Setembro with his 82nd-minute strike.
The result stretched the Teranga Lions' unbeaten streak to four games with 12 points in Group I while Congo trail in second spot with six points, although with a game to play against Eswatini on Monday.
Sunday's effort made Mane the joint-top scorer in the group with three goals, alongside Famara Diedhiou who scored a hat-trick against Eswatini in November 2019.
The Liverpool star who was on target against Guinea-Bissau in Thies four days ago, and Napoli defender Kalidou Koulibaly played for 90 minutes while Watford’s Ismaila Sarr was replaced in the 79th minute.
Senegal have now qualified for their 16th Africa Cup of Nations tournament and they will be aiming to win their maiden title in Cameroon 2022 after finishing as runners-up in Egypt last year - they suffered a 1-0 loss against Algeria in the final.
The qualification comes as another feat for Aliou Cisse who has now guided the West African country to three successive editions of the continental showpiece without losing a game in the qualifying stage.
The former Senegal captain who was appointed as national team coach in 2015, also led the Teranga Lions to the 2018 Fifa World Cup in Russia.
Aliou Cisse's men will hope to end their campaign on a flying note next year, when they visit Congo for their next group game on March 22 before hosting Ewastini on home soil eight days later.
