Belgium cruised through to the World Cup last 16 with Romelu Lukaku’s two first-half goals proving decisive in a comfortable 5-2 success over Tunisia.

In sweltering 40C heat and humid conditions in the Otkrytiye Arena, it did not take long for Roberto Sanchez’s side to get off the mark.

Eden Hazard was felled by Ben Mustapha and the Belgium skipper calmly slotted home the resulting spot-kick with just six minutes gone.

A flowing move six minutes later almost brought a second. Thomas Meunier skipped forward and released Lukaku down the right flank and his low cross was turned goalward by Hazard, but his connection was not altogether solid and Ben Moustapha saved easily, low down to his left.

Batshuayi also got the fifth goal which was the most difficult of his chances in the 90th minute when sliding in to divert substitute Youri Tielemans’s superb crossfield pass into the net to make it 5-1.

In the final minute of stoppage time, Khazri turned in a Tunisian consolation, to give England hope of their upcoming clash with Belgium.
