OLD FOES: In their last meeting in May 2013, the Rode Duivels won 4-2 in Cleveland. Kevin Mirallas and Marouane Fellaini both scored for Belgium, while Clint Dempsey and Geoff Cameron were on the score sheet for the US.
ONE OFF: Belgium won all three of their group games at a World Cup for the first time. It was also the first time they had won three successive games in the competition.
NOTHING TO BRAG ABOUT: Only Iran (30%) had a lower average possession figure in the group stage than Jurgen Klinsmann's side (39%).
LATE FINISHERS: The last six Belgian goals at World Cups have come in the closing 20 minutes of games.
NEEDS A BIB: Only three players (Lionel Messi, Alexis Sanchez and Angel Di Maria) completed more dribbles than Eden Hazard in the group stage (13).
SOLID AS A ROCK: No player made more blocks than Daniel van Buyten in the group stage (5).
Phew, glad that's over. Time for a soda and fries.
Who can forget that. What a goal. Super Clint.
Big there from Roonaldo. My question is: who's not supporting the US of A today?
10 minutes until kickoff! Tweet your predictions using #WTOPspin...
Just under 10 minutes to go. Excited? Nervous? Terrified? Hiding behind the sofa?
And the teams are coming out....
Star Spangled Banner being belted out by the USA team. Apart from Clint of course.
Right, here we go. Do you believe that they will win? Because it seems that pretty much everyone on planet earth does, but only time will tell. Stay with us for the next 90, or 120, or penalties. Or however long it goes. Let's go.
Anthems have been sung, teams are on the pitch and we're ready for the round of 16 match between the U.S. and Belgium
