Tunisia qualified for the World Cup after winning the group with 14 points.
Morocco qualified for a first World Cup since 1998 after beating their closest Group C challengers Ivory Coast 2-0 away from home on Saturday.
However, after weathering an early storm, including a potential penalty call, Morocco scored two goals in the space of five minutes to put themselves on their way to the finals, where their last appearance was in France in 1998.
Nabil Dirar gave the visitors the lead 25 minutes into the game, cutting in from the right and seeing his left-footed cross go all the way in, raising serious questions over Sylvain Gbohouo goalkeeping.
"Therefore you have to play without sparing yourself in order to win it...but defeat never crossed my mind" Renard who coached the Ivorians to the 2015 title of the African Nations Cup in Equatorial Guinea said.

Serge Aurier had the best chance to score for Ivory Coast in the second half, but he skied his shot over the bar, and Morocco maintained their record of not conceding a single goal in the six games in CAF qualifying Group C.
Had Tunisia lost, they would have ceded top place to DR Congo, who finished strongly to overcome Guinea 3-1.
Tunisia's point ensures their fifth World Cup participation - and their first since 2006 - but ensures that the Democratic Republic of Congo's wait to return to the global showpiece for the first time since 1974 will continue. The Tunisians held on for the draw, though, and it turned out to be a precious point.
Morocco ended their 20 years wait for a World Cup ticket when they beat the Elephants of Ivory Coast 2-0 in front of their home fans.
