IT’S a tough one to call in today’s World Cup round of 16 games.

Argentina will fancy themselves against Switzerland in the 5pm game, after the latter scraped through the group stage, but momentum could be enough for the Swiss to spring a surprise.

Sasha Hasatroudi, who lives in Bournemouth, is following the country of his birth, Switzerland.

He said: “It was a really good game (the final group game), probably the best they have played so far.

“It’s the result you want to go and play Argentina.

“It’s not an easy game, but if you can keep Messi quiet it makes it a lot easier, but it’s easier said than done – he can pop up at any point and change a game.”

Perhaps the more difficult game to predict is Belgium against USA in the 9pm kick-off.

Both teams are improving on their past reputations, with Belgium seemingly in particularly good form and the USA nipping through their group on goal difference.

Vianna Renaud, who works at Bournemouth University, is cheering on her home country, the USA.

She said: “Another all-or-nothing game for Belgium and the US!

“While rumour has it that Klinsmann is keeping the US team positive, the stakes are too high not to carefully consider the facts.

“The Belgium team is relatively young, but have been playing well, ranked 11th going into the World Cup.

“For the US, ranked 13th, the best news is that Jozy Altidore will be back.

“However injury is still a major concern for both teams with Vincent Kompany and Thomas Vermaebn, both key parts of the Belgium force, being out.

“In any case let us hope the US can keep that positivity going; I think they will definitely need it!”
