Brad Guzan continues his Olympic quest tomorrow as the USA tackle Holland in the second group game.

And the Villa keeper believes his compatriots have a secret weapon in the bid to beat the likes of Royston Drenthe and Ryan Babel - Michael Bradley who plays his club football for Dutch side Heerenveen.

The Americans got off to a great start earlier this week as Guzan kept a clean-sheet in the 1-0 victory against Japan.

Holland will provide an even stiffer test but Guzan is hoping Bradley's inside track will prove invaluable.

He said: "Of course Michael is telling us who to look out for and maybe giving us a little insight into the way the Dutch will play.

"But if we didn't know that they were going to be a tough test before now, then we'd be in trouble. We know they're a really good team.

"We'll watch the DVD (of the Dutch), make sure we cut out the little mistakes we made against Japan and be ready to go."
