"I believe that we will win" may be the American fans' chant of choice as they flock to Brazil to cheer on their country but the odds are stacked against the USA proving their supporters right when they tackle a Belgium side unbeaten in competitive games since 2011.
Belgium may not have dropped a point in Brazil yet, but they haven't set the tournament alight either. With the humidity set to rise towards 80 per cent in Salvador, Jurgen Klinsmann will be hoping the Belgians finally wilt in the heat.
Team USA need more firepower
If the Americans are to cause an upset and build on the growing excitement back home then they are going to have to create more in the final third. Only two sides have taken fewer shots than the USA's measly 23 and they are coming up against a Belgium outfit who have conceded just one goal - the best record of any side. Thibaut Courtois - who has never lost a game as Belgium's goalkeeper - has barely been tested across the 270 minutes they have played. Only four keepers have faced fewer efforts than the 26 he has had to deal with. The USA will therefore have to up their game if they are going to create the opportunities necessary to reach the quarter finals.
Don't expect early fun in the sun
It is hard to imagine that this will be a four or five goal thriller. While many viewers may be surprised by Belgium's lack of goals, having imagined them as a free-scoring squad, the truth is that this tournament has echoed their goalscoring form in the last 12 months. In their 14 internationals since they thumped the USA 4-2 in May 2013, Belgium have only scored more than two goals on one occasion and that was a pre-tournament thrashing of Luxembourg. The USA have one of the tournament's most permissive defences though, with only Ecuador and Colombia having faced more shots at goal than their 47, so this could be the match where Belgium's shackles finally come off.
More Belgian waffle?
Belgium's group games followed a very familiar pattern with the Red Devils keeping possession but hardly threatening until the final 20 minutes - when the game opened up and every one of their goals at this tournament have arrived. Three of those have been scored after the 75th minute, which should be worrying for the USA. Half of the goals that the Americans have conceded so far have arrived in the final quarter of an hour - most notably Portugal's last-gasp equaliser. This mirrors a problem they experienced in qualifying when 36 per cent of goals they conceded arrived in this period.
With both sides harbouring genuine ambitions of progress, expect a hot and hard-fought affair that could last the full distance if the USA can stay switched on for 90 minutes. The numbers suggest that Belgium won't get a better opportunity to justify their pre-tournament hype as 'dark horses', even if they have to bide their time.
