A win for Belgium in their Group G clash would guarantee their place in the knockout stages while Tunisia are fighting desperately just to stay alive in the tournament.
Here are our key player match ups.
Romelu Lukaku (Belgium) v Wahbi Khazri (Tunisia)
The Manchester United marksmen scored twice in the 3-0 victory over Panama and one more goal will make him the top-scoring Belgian in major tournaments: Lukaku has five, just one behind Jan Ceulemans.
With service provided by playmakers like Eden Hazard and Kevin de Bruyne, Lukaku’s job is much easier than Wahbi Khazri from the Eagles of Carthage.
The all-action midfielder was not able to influence the game the way he would have liked against England due to a lack of possession but will again be tasked with dictating the Tunisia attack.
Dedryck Boyata (Belgium) v Syam Ben Youssef (Tunisia)
Ben Youssef was outstanding against England and no one did more than the Kasimpasa centre half to earn Tunisia what looked like a well-deserved draw.
He constantly thwarted England’s raids with a game high four tackles. He was also outstanding in getting things re-started from the back with a 88% success pass rate – 21 accurate passes out of a total of 26.
Filling in for the injured Vincent Kompany and Thomas Vermaelen, Dedryck Boyata will keep his place in central defence for the Red Devils. Boyata was solid against Panama winning a game high eight aerial duals and a total of 93 touches. Tunisia must get through him to score.
Kevin de Bruyne (Belgium) v Ferjani Sassi (Tunisia)
The world is waiting, holding its breath, for Belgium wizard de Bruyne to perform the way he can on the World Cup stage. The Manchester City superstar had a tepid game against Panama by his lofty standards.
He had three shots at goal, with just one on target, a pass success rate of just 78% (57 accurate passes from a total of 73) but he did create four chances with one neatly converted by Lukaku, for a solitary assist.
Sassi for his part was at his very best against England, with two shots on target, two tackles and a coolly slotted penalty. Tunisia again will need a double shift from the Al Nassr midfielder.
