Both sides had plenty of chances, with France taking 19 shots to Belgium's nine, but only Umtiti's 51st-minute header following Antoine Griezmann's corner found the back of the net. The match kicks-off at 20:00 hrs (BST) at Krestovsky Stadium in St. Petersburg.
Some echoed the love-hate relationship and inferiority complex many French-speaking Walons have with their bigger neighbour France.
Belgium has finally lived up to the hype surrounding them!
And the presence of French World Cup victor Thierry Henry on the Belgian coaching staff as one of Martinez's assistants adds extra spice to the occasion. He said after that match that there he was disappointed that they were done in by a set-piece.
"We wanted to get into the final", he said.
"We've been great so far in the World Cup", Debregeas said. With Hazard, Romelu Lukaku and Kevin De Bruyne, they lost in the 2014 World Cup quarter-finals and at the same stage at Euro 2016, but under Roberto Martinez in Russian Federation they have already taken an extra step after stunning Brazil in the last eight in Kazan. Roberto Martinez's men arrive to the semifinals with a lot of momentum their way heading into this match, but France is not going to be an easy opponent. In fact, four of Belgium's five games have witnessed over 2.5 goals scored.
Kompany, an injury-prone 32-year-old who may well have played his last World Cup in Russian Federation, believes that, despite the loss, the class of 2018 has done his nation a favor.
Belgium threatened down the flanks and Eden Hazard put in a risky cross which was turned behind by Umtiti - though the resulting corner was wasted by Nacer Chadli, playing in an unfamiliar right-back role.
France had their best chance with less than 10 minutes of the first half to go. The French will be hopeful of winning their second World Cup.
The first yellow card of the game was issued to Belgium's Eden Hazard, who pulls Matuidi to ground to prevent a France counter-attack and shortly following was Alderweireld who picked up Belgium's second booking. I thought it was unbelievable how he did it, how he worked it out and how the players did it.
"It's really too bad to lose to France, Belgium's national bad luck", Alice Cordier told AFP in a fan zone in Waterloo, south of the capital Brussels.
"We could easily have frozen".
