Belgium qualified for next year's World Cup finals and kept up their unbeaten qualifying run as they beat Estonia 3-1 in Brussels on Saturday.
Manager Roberto Martinez's side, semi-finalists in Russia in 2018, climbed to an unassailable 19 points in Group E as striker Christian Benteke scored early, while wingers Yannick Carrasco and Thorgan Hazard added second-half goals.
But it was in fact a wasteful display from Belgium, whose supporters were expecting more of a goal feast at the King Baudouin Stadium to celebrate qualifying for a third successive World Cup.
He tapped-in from close range after Estonia goalkeeper Matvei Igonen made a horrible error, letting a low cross from Carrasco slip through his hands.
Carrasco showed the way after Benteke had set him up in the 52nd minute with a powerful left-footed drive into the top of the net from the edge of the area.
But Estonia then pulled one goal back when Rauno Sappinen's shot was palmed away by Belgium goalkeeper Thibaut Courtois into the path of Erik Sorga, who cut the deficit in the 70th minute.
It was four minutes later that the two-goal advantage was restored when substitute Thorgan Hazard headed home De Bruyne's cross.
Belgium, who are top of the FIFA rankings despite a quarterfinal exit at the European Championship and fourth place at last month's Nations League finals, will finish their qualifying campaign away against Wales in Cardiff on Tuesday.
