Sadio Mane's side lead Group B after goalless draw against Guinea

Liverpool teammates Sadio Mane and Naby Keita became rivals on Friday, captaining Senegal and Guinea in a drab 0-0 Group B matchday 2 deadlock at the Africa Cup of Nations.

Scoring chances were few in the afternoon heat of Bafoussam with Senegal the more wasteful side in a showdown between nations expected to occupy the top two positions in the final standings.

Guinea and Senegal will go into the final round of group matches on Tuesday sharing the lead with four points each, and goal difference could determine who finishes first.

Malawi and Zimbabwe meet later on Friday in the second match of a double-header with both needing maximum points to have a realistic chance of reaching the second round.

While neither southern Africa country is likely to overtake Guinea or Senegal, a win could take them into the round of 16 as one the best four third-placed teams.

It was the third clash between the west African neighbours with Senegal winning the previous two by one-goal margins in 1994 and 2006.

Senegal midfielder Idrissa Gueye was ruled out after testing positive for coronavirus and joined fellow stars Edouard Mendy and Kalidou Koulibaly in isolation.
