Romelu Lukaku says the Red Devils are going all out to win the World Cup before their golden generation breaks up.
The Manchester United striker has suggested the Red Devils will have to wait a long time to have a better chance of lifting the trophy than they do this year.
"This might be the last tournament for our generation because a few players are going to retire so we're playing for them and trying to leave a bit of history," he told the UK's BBC Radio 5 live.
Tottenham Hotspur midfielder Mousa Dembele, aged 30, has already hinted at international retirement after the tournament in Russia.
It's likely to also be the last shot for Vincent Kompany (32), Thomas Vermaelen (32), Jan Vertonghen (31) and Dries Mertens (31).
Only five of Belgium's 23-man squad are under the age of 25.
The gifted group's first tournament together was the 2014 World Cup in Brazil, where they won all three group games, but stuttered past the USA in the round of 16 and fell to Argentina in the quarter-finals.
They were eliminated by Wales at the same stage of Euro 2016.
"In the last tournaments that we played, we set the bar so high then we didn't reach our objectives. Now we're just trying to enjoy it," said Lukaku.
"Football is all about having fun - but playing to win at the same time. When you find the right balance there's so much more to enjoy."
He enjoyed himself last night alright, netting a brace for the third match running as Belgium turned on the style to tear into Tunisia and earn a 5-2 win last night.
He now sits top of the goalscoring charts on four, level with Cristiano Ronaldo.
"We played much better than we did in the first game. Now we have to keep our head day after day, give our maximum and hopefully perform better game after game," added Lukaku.
"I'm delighted for Eden (Hazard, who also scored twice) to come to the forefront as well because we need players like him to perform. He did it again today."
Lukaku was withdrawn late on after a knock to his foot, but he fully expects to be ready and raring to go again when his team face England on Friday morning AEST.
