In the Football World Cup's final two Round-of-16 matches tonight, Argentina will take on Switzerland, and Belgium will clash with the US.

The Argentina-Switzerland match will begin at 9:30 PM Indian Time at S?o Paulo, while the Belgium-US game will kick off at 1:30 AM at Salvador.

All India Radio will broadcast live commentary on both the matches. It can be heard on FM Rainbow, Rajdhani and national channel. You can also listen to the preview of the matches in our major bulletins at 2 PM and 9 PM.

Belgium, the team which entered this World Cup burdened with great hopes, will tonight clash with the US, the side that has been more than a little erratic so far. The US, in their three group matches, had defeated Ghana, drew with Portugal and lost to Germany.

Belgium, on the other hand, was the fourth team, after Netherlands, Argentina and Colombia, in the group stage finishing with full 9 points. While US have their full strength team available, Belgium head into the game with injuries and suspension.

Full-back Vanden Borre will miss the rest of the tournament due to a broken ankle, while midfielder Steven Defour is suspended. Thomas Vermaelen is also unavailable, with Vincent Kompany a little unfit. But, Belgium still has a plethora of talented players, like Lukaku, Hazard, Fellaini and van Buyten.

And if the Americans play like they did against Germany, it could be an easy passage for Belgium to the last-8, their second best World Cup outing after 1986, when they reached the semi-finals in Mexico. But if Jones, Zusi, Dempsey and Altidore play as a unit, we may well see the US taking on either Argentina or Switzerland in the quarterfinals.

The teams that have already advanced to the quarterfinals are: Hosts Brazil, Netherlands, Germany, France, Colombia and Costa Rica.
