Group B leaders Tunisia beat Mauritania in a Matchday 3 FIFA 2022 World Cup qualifier on Thursday night to move to 9 points on the log.

Mauritania are pointless.
On Sunday, Zambia welcome Nzalang Nacional at home while Tunisia will be away against Mauritania.
The Chipolopolo Boys will be hoping to redeem themselves after losing two successive qualifiers.
