They may have been criticised for their perceived negativity, but this Belgium side have got an awful lot going for them. Their third win in three group H games was achieved the hard way, playing with 10 men for half the game against a South Korea side that really went for it. They're hard to break down, keep going to the bitter end, and have plenty of flair players who have yet to make their mark on the tournament. The USA will not be relishing the prospect of facing them in the last 16. As for South Korea, they depart the tournament having given a fine account of themselves – on another night, their second-half energy and positivity might well have got them the goals they needed to progress.
