PORTLAND, Ore. — Wondering how to drive it like Dempsey, move it like Messi or rip it like Ronaldo?

There’s an app for that.

As Argentina and Germany prepare for Sunday’s World Cup final, companies that produce soccer-related merchandise are already winning.

The once-every-four-years consumer frenzy, dubbed by some as the “World Cup Effect,” drives the sale of everything from the traditional jerseys and cleats to unusual items such as team-endorsed windshield wiper fluid to Versace T-shirts and, yes, mobile phone apps.

The stakes are highest for sports shoe and apparel giants Nike and Adidas, who are wrestling for dominance of the soccer market.
