The Red Devils – ranked number one in the world – made it three wins from three in this batch of qualifiers to all but ensure their place at Qatar.

With 16 points to their name, Belgium need just one win from their remaining two fixtures to seal top spot in Group E, with Dennis Praet's goal the difference on Wednesday.

Shorn of Romelu Lukaku and Kevin De Bruyne, Belgium did not make the most of their dominance, yet Belarus never threatened a comeback.

Toby Alderweireld played in a cross De Bruyne would have been proud of from the right-hand channel in the 20th minute – the ball falling to Batshuayi, who dragged his attempt wide.

Batshuayi headed in the rebound from Dedryck Boyata's effort against the crossbar soon after, only for the offside flag to cut short his celebrations.

Belgium had their lead two minutes later, however – Praet sweeping home across Sergey Chernik.

Dodi Lukebakio stretched his legs early in the second half, though made a poor decision to shoot from the edge of the area rather than slide in Leandro Trossard.

Batshuayi's search for a goal continued to prove fruitless as he saw an effort kept out by Chernik, Belgium missing the cutting edge to make the scoreline as comfortable as their performance warranted.

Artem Bykov tried to make them pay with a hopeful long-range attempt, but it never came close to testing Koen Casteels as Belgium eased to victory – Eden Hazard seeing a late free-kick saved well by Chernik at the other end.
