"I think there was a coach who once said about their team that they're quite easy to analyse but quite hard to beat".
The coach said having Thierry Henry, who was in France's 1998 World Cup-winning squad, among his backroom staff has helped bridge that gap.
Belgium took advantage of some an overly attacking Brazilian approach at the Kazan Arena to take a 2-0 lead by half-time.
"Although our team will be better in two years with more life experience, maybe the cards on injuries and things won't fall as kindly and we won't get this opportunity again", he told ITV News.
"We are a team and we are all happy to be here", said Andersson, who explained that his players have now spent 45 days together.More news: Kompany: Belgium losing no sleep over Brazil
France is moving on to the semi-finals for the first time since 2006, after a 2-0 win over Uruguay.
Maradona has since apologised to Federation Internationale de Football Association and its referees, saying he was "overcome by emotion in cheering for Colombia".
In stark contrast to their 4-3 win over Argentina in the last 16, France struggled to create clear-cut chances against an organised Uruguay side, and won thanks to a glancing Raphael Varane header from a free-kick before Fernando Muslera's error gifted Antoine Griezmann a second.
"I've already said enough about Cavani. It's something I see day in day out and I love Uruguayans and Uruguayan culture, so I have a lot of respect for them".
With three goals to his name, the same as his teammate Kylian Mbappe, Griezmann stressed that his team could go all the way. France goalkeeper Hugo Lloris dived to his right and got a hand on a header from Martin Caceres, pushing it just wide of the goal.
"If you want to achieve something, you have to fight for it every time", said Lukaku, who has impressed at the World Cup with four goals and is second in the Golden Boot race, behind England's Harry Kane with six. "We've improved points on balance since the last match and all these games are important to build confidence". "Nothing is over for us today".
