While fellow North African countries, Algeria, Morocco and host Egypt, secured maximum points in the group stage, the Carthage Eagles squeezed into the Round of 16 after they played another uninspiring barren draw against Mauritania on Tuesday.
Though the aim of making it out from the group stage has been achieved, the Tunisia coach has reiterated the need for the Eagles to now take full flight in the knockout phase.
“We have finished a stage and now we have to tackle another one, but with different challenges,” the French coach told the media in Egypt.
“Three draws in the group stage does not satisfy us. It's up to us to review all this, even if the main aim was to qualify.
“We are going to learn and we have to prepare well for the rest of the competition.
Tuesday’s result is the first time Tunisia played a goalless draw in any Afcon game since January 2010 against Gabon.
Nonetheless, the Carthage Eagles have now progressed to the knockout stage at the Afcon in 10 of last 13 editions of the tournament.
