Romelu Lukaku ended Denmark's valiant effort with two second-half goals as Belgium joined France, Italy and Spain in next year's UEFA Nations League final four.
Match in brief
Lukaku struck twice in the second half to all but end Denmark's challenge for a finals spot in a thrilling encounter in Leuven. The game was not three minutes old when Youri Tielemans opened the scoring, but Denmark were not cowed.
Jonas Wind soon marked his full debut with a goal, and the visitors had chances to go ahead themselves before Lukaku's opportunistic strike made it 2-1 some 11 minutes after the break. His second, a trademark header, gave Belgium breathing space.
There was a late hiccup, however, when Thibaut Courtois allowed Nacer Chadli's pass to slip under his foot, but Kevin De Bruyne hit back immediately to rubber-stamp progress.

They say it's all about putting away your chances at the top level, and that's precisely what Belgium did better than Denmark. The visitors came close before and after the interval, but it was Lukaku's eye for goal that undid them in the end. Not a vintage showing by the Red Devils, but they preserved their 100% home record in the UEFA Nations League to progress. Can’t argue with that.

Denmark played their hand, but you can't deny Belgium's class. The bold choice to start with Wind proved astute – and not just because of his goal. The Danes leave without points, but not empty-handed. This performance proved they can be a handful even for the best in the world.
Romelu Lukaku, Belgium forward: "Sometimes you need to be a bit scrappy to win, and we did that tonight. We were close last time [to qualifying for the UEFA Nations League finals], but we lost pretty harshly to Switzerland. We knew that a point would be enough, but you don’t want to risk it, so we won and we’re really happy about that."
Kasper Hjulmand, Denmark coach: "We played with a lot of defensive discipline. We were good on the ball, we created chances. Martin [Braithwaite] had a big chance to score and make it 2-1. So there are a lot of positives that we can take with us, and some things that we have to learn from. No doubt about that."
