Romelu Lukaku and Eden Hazard both scored twice as Belgium strengthened their lead above England at the top of World Cup Group G by crushing Tunisia with a devastating attacking display.
While Roberto Martinezâ€™s side are not through to the last 16 yet, a win for England over Panama in Nizhny Novgorod today will see the Red Devils and Three Lions progress.
That would leave their meeting in Kaliningrad on Thursday to decide who tops the group and it is Belgium who hold the upper hand there, with their sparkling finishing in the sunshine at the Spartak Stadium leaving their goal difference significantly better off.
Speaking after the game, Martinez said he would make â€œmajor changesâ€ for the match against England.
â€œIf we could have seven days to prepare for that game and then another seven days before the following game then we would start with the same starting XI,â€ said the former Everton boss.
â€œThe reality is that we have qualified – you are only as good as the 23 players. There will be opportunities for others. We need to check the injury doubts Lukaku (ankle), Hazard (calf) and Mertens (knock to ankle).â€
Belgium attacked from the off and needed only five minutes to take the lead, when Hazard was barged over by Syam Ben Youssef just inside the box and got up to send Tunisia keeper Farouk Ben Mustapha the wrong way from the spot.
Things quickly got worse for Tunisia when Ali Maaloulâ€™s heavy touch on the halfway line allowed Dries Mertens to nip in and release Lukaku, who found a perfect low finish.
The North African side, needing a win to reignite their own hopes of progress, gave themselves hope when Dylan Bronn got on the end of Wahbi Khazriâ€™s whipped free-kick just 109 seconds later.
But they could not compete with Belgiumâ€™s vastly superior firepower and Lukaku gave the Red Devils breathing space once more with a dinked finish from a Thomas Meunier pass just before half-time.
Hazard added his second goal soon after the break, racing on to a precise Toby Alderweireld pass and rounding the keeper to fire home.
That made sure of the points, but Belgium were not finished yet. Substitute Michy Batshuayi, who also had a shot cleared off the line and hit the bar from close range, finally found the target from Youri Tielemansâ€™ cross.
Tunisia did manage a late consolation, when Khazri swept home Hamdi Nagguezâ€™s cross but, unless Panama beat England, they will become the third African team to be eliminated, leaving Nigeria and Senegal to carry their continentâ€™s hopes.
