In the 16th minute, Ismaila Sarr gave Senegal the lead, and midway through the second half, Habib Diallo increased their advantage to 2-0.
Jean-Charles Castelletto’s header in the 83rd minute narrowed the gap, setting the stage for a tense finale. However, despite George-Kevin Nkoudou missing a free header that could have equalized, Sadio Mane secured the victory in stoppage time.
Senegal will secure the top spot in Group C if they avoid defeat in their final group match against Guinea on Tuesday at 17:00 GMT. Guinea currently holds the second position in the table after defeating The Gambia 1-0 on Friday. This result implies that Cameroon will likely need a victory against The Scorpions on Tuesday at 17:00 GMT to progress to the knockout stages.
Cameroon, a five-time continental champion with one point from two games, could advance as one of the four best third-placed teams unless they surpass Guinea in goal difference or goals scored.
Andre Onana returned to the goal for Cameroon after missing their previous match against Guinea due to his decision to play for Manchester United in the Premier League. However, he faced criticism for Senegal’s opening goal, as his clearing punch from a corner was headed back into the box by Pape Matar Sarr, allowing Ismaila Sarr to score.
Senegal extended their lead in the 71st minute through Habib Diallo, who slotted home Ismaila Sarr’s low ball after some skillful interplay.
Cameroon, lacking a significant threat up front, came to life in the final 10 minutes. Castelletto’s powerful header from Olivier Ntcham’s cross following a short corner brought them back into contention.
Despite pressing forward for an equalizer, Nkoudou missed a crucial chance in the 94th minute, diverting a right-wing cross wide at the back post. Senegal capitalized on the opportunity, as Sadio Mane calmly guided Idrissa Gana Gueye’s pass into the bottom left-hand corner, securing the three points.
Senegal, led by Aliou Cisse, who guided them to their first Afcon title two years ago, has begun their title defense impressively, aiming to become the first side to retain the trophy since Egypt in 2010.
