Belgium coach Marc Wilmots talked up his team's pragmatic approach again after they edged South Korea 1-0 on Thursday.
Considered serious challengers at the FIFA World Cup, Belgium claimed three wins in Group H without being overly impressive.
Wilmots' men have battled past Algeria (2-1), Russia (1-0) and South Korea without hitting their best form.
But the 45-year-old coach, whose team played the second half with 10 men, said their job was simply to win.
"Yet again our patient approach paid off," Wilmots said.
"I knew that the Koreans would leave us with a lot of space to play with. My young team had a tendency to push forwards too much at times, so I tried to get them to relax a little.
"It’s no easy task to finish the group stage with nine points. It’s a truly historic achievement for Belgium, and I’d like to congratulate the staff and all the players.
"We're here to win, not to play beautiful football, and we've accomplished our mission."
Midfielder Steven Defour was sent off just before half-time for a reckless, studs-up challenge.
Defender Jan Vertonghen scored the match-winning goal in the 78th minute at the Arena Corinthians in Sao Paulo.
The Tottenham centre-back was delighted, particularly with his side's ability to claim a win with a man less.
"After scoring, I wanted to share my indescribable joy with our supporters. We feel like they’re really behind us, and that’s important for the squad," Vertonghen said.
"Finishing top of the group and pulling off a late win with 10 men is also a real source of satisfaction."
