Nike is following up its great 2010 World Cup campaign with a really cool, albeit smaller, interactive play for the Euro Cup.

In a program called "The Chance", Nike sent scouts to 50 countries to find the next 100 potential soccer stars.  Here, the winners are all shown crashing a game between France and Netherlands.  Scattered throughout are all kinds of international sports stars (even Lebron James).  Inside the youtube video are 9 interactive 'tunnels' to get additional information on players, stats, Nike product info, etc. 

Like the World Cup ad, it's global in reach, designed to go viral, and connects to other brand touchpoints online.  Searching for the 9 tunnels is a also a cool tactic to really get viewers to focus on the content of the ad.
