Mel Young has launched the #passforhome challenge, an initiative that began in Edinburgh, Scotland, and will travel through the international teams taking part in the tournament to reach the South Korean capital just one day before the event begins.

The challenge began in the iconic British city, which is home to the Homeless World Cup headquarters and hosted the tournament in 2005. The ball was sent to Brazil, which hosted the 2010 event in Rio de Janeiro, and will continue its journey through the competing nations before arriving in Seoul, the capital of South Korea.

The #passforhome campaign was launched in Korea earlier this year, with Tottenham Hotspur and South Korea's star striker Heung-Min Son helping to raise awareness of the tournament.

Local organising committee chairman and former professional footballer Keun-Ho Lee also took part in the challenge to promote the tournament, which will take place over a week from 21-28 September at private research university Hanyang University.

This year's edition will see 49 nations, 64 teams and 500 players compete over 8 days in a celebration of football, friendship and culture. The event brings together the best homeless footballers from around the world, promoting integration and understanding between different cultures.

It is estimated that around 100 million people worldwide (equivalent to the combined populations of the UK, Netherlands, Belgium and Portugal) are homeless, with up to 1 billion people lacking adequate shelter.

The homelessness crisis is complex and multifaceted, involving social exclusion, stigma, economic hardship, poverty and physical and mental health problems.

The aim of the World Cup for the Homeless is to contribute to an end to this global crisis in all its forms and to work towards the creation of a valuable space for human reintegration.

At the beginning of August, FIFA signed a Memorandum of Understanding to support the Homeless World Cup Foundation (HWCF), which organises the Homeless World Cup. The main objective is to support and motivate homeless people to change their lives.

"I am delighted that FIFA is supporting this wonderful championship and partnering with the Homeless World Cup Foundation," said Infantino. "It is a perfect example of how football can bring people together to improve lives," the FIFA President added.
