We are very proud to be associated with Street Soccer and all the fantastic work they do, and look forward to following these inspirational players as they take on the rest of the world in the tournament.

“We work closely with Abhijeet Barse, co-founder and CEO of Slum Soccer, and his team in sharing experiences and our coach Andy Hook regularly travels to India to help out the project there, and so we have strong ties, demonstrating the power of football in helping overcome some of the challenges social exclusion brings.”
