Lionel Messi's Argentina aim to put a shambolic World Cup build-up behind them and make a statement in their opening match against tournament debutants Iceland today. But Iceland's Burnley winger Johann Berg Gudmundsson said the minnows are confident of stopping the Argentina captain in the Group 'D' clash. Spurred on by their fans' thunderous "Viking clap", they earned a 1-1 draw with Cristiano Ronaldo's Portugal, then famously dumped out England to reach the quarter-finals.

"We kept Ronaldo quiet so hopefully we can do the same against Messi," Gudmundsson said. "We know we're probably going to be defending for a lot of the time and obviously he's one of the best players in the world and he can turn it on." But Messi is a man on a mission as he chases his first World Cup winner's medal and will not tolerate complacency against the minnows at Moscow's Spartak stadium.
