Tunisia need just a point from their final Group B clash with Zimbabwe in Libreville on Monday to advance to the quarterfinals of the 2017 African Nations Cup finals and at the same time knock out North African rivals Algeria.
Tunisia are second in the pool with three points, three behind Senegal, who have already been crowned as winners of the group, and two in front of Algeria and Zimbabwe.
The only way they can now be eliminated from the competition is with defeat to a Zimbabwe side that packs plenty of attacking talent, but have proven vulnerable at the back.
The only previous meeting between Tunisia and Zimbabwe was a friendly in 1998 that finished in a 1-1 draw, but the North Africans will be heavily tipped to come away with a win this time round.
Tunisia have qualified for the quarterfinals in five of the last seven tournaments they have played, but have not made it past that stage since winning the title on home soil in 2014.
