Mourinho is serving as Yahoo's 2014 Global Football Ambassador.
Countries across Asia have hosted events in connection with the campaign, including Australia, Indonesia, Hong Kong, India, Vietnam, Malaysia and Singapore.
For example, in Hong Kong Yahoo created a dedicated Chinese-language web page and carried out a 'guerilla' event in a local park on 18 and 25 May. There, budding football stars got the chance to enter the challenge by taking a 10-second video showing off their football skills. The company provided 300 video cameras for the event.
As of last week, the worldwide campaign had received more than 1,000 video submissions on its worldwide Tumblr, and the number is expected to keep growing until the campaign ends on 27 June. The results will be announced in July. Five favourites will be invited to the UK for the training session, which will take place between 4 and 10 September.
Mourinho will also be providing commentary and opinions on the World Cup through Yahoo's network and platform, where fans will also have access to his own daily world through photos and video.
