Tunisia will be hoping to avoid an early upset as they face newcomers Rwanda in the opening match of the 2004 African Cup of Nations.
The hosts are one of the favourites for the title and will be expected to cruise past the minnows in front of a 60,000 capacity Stade Rades on Saturday.
"This is a big match. The pressure on us is huge and I hope that the players have taken in what I have told them," said Tunisia coach Roger Lemerre.
"But sport is full of surprises and anything can happen, especially in football - I should know."
There is a big question mark hanging over the fitness of star defender Hatem Trabelsi.
The Ajax Amsterdam player could miss the game having not fully recovered from an injury he sustained eight weeks ago.
Etoile Sahel defender Karim Hagui is likely to make his first Cup of Nations appearance if Trabelsi is declared unfit, while Club Africain star Karim Saidi is set for his debut at left-back.
Rwanda have been training behind closed doors at their base in Bizerte since their arrival earlier in the week.
Their Serb coach Ratomir Dujkovic has already resigned himself to the fact his team will not win the Cup of Nations and instead is just thankful they can take their place in the event.
"This is a chance to learn from better teams," said Dujkovic.
"We have no chance of winning the Cup of Nations, but the Tunisians will have to suffer to beat us.
"We are a poor nation and playing here is heaven for us especially with all the problems and tragedies the nation has endured."
Rwanda have no injury concerns with striker Desire Mbonabucya likely to lead the side out as captain.
