Manchester United ace Cristiano Ronaldo was armed with a secret weapon for his stunning hat-trick scored in Saturday's 6-0 romp over Newcastle.

The Portuguese star was wearing Nike's new Mercurial Vapor IV boots for the first time in a match. Ronaldo had previously worn the boots for Nike's internet video in which he appears to beat the world's fastest road car in a race!

Ronaldo was consulted by Nike in the design process, as were other top Premier League players including Chelsea's Didier Drogba and Arsenal's Theo Walcott.
