Researchers from a Glasgow university have published a paper that suggests Manchester United footballer Marcus Rashford's social activism should be the "blueprint" for high-profile athletes.

The paper was jointly examined by Glasgow Caledonian University and the University of Alabama using the England star's campaign to support vulnerable children during the lockdown as a case study.

It demonstrated what sporting icons can learn from Rashford, in a new paper for the International Journal of Sport Communication.

The study analysed more than 400 news stories and Rashford's posts on Facebook, Instagram, and Twitter from January 2020 to December 2021.

Researchers tracked how Rashford's push to ensure no child in need went hungry culminated in the UK Government reversing its decision on free school meal vouchers.

The "humble, dignified and calm narratives" Rashford employed were critical in gaining public backing, the study highlighted.

The social activism led to the establishment of a child poverty taskforce supported by some of the UK's largest brands and supermarkets.

Professor John Harris, of Glasgow Caledonian University and co-author of the paper, said: "This case study showed that Rashford understood how to use his position to leverage his appeal to inspire social change and make a positive difference.

"Social media has provided celebrity athletes like Marcus Rashford with a platform to communicate openly and authentically with fans.

"Rashford was able to speak with a sincerity and sensitivity that resonated with his millions of fans, social media followers, and the public alike."

The study, A Case Study of Marcus Rashford: The People’s Champion, a “National Treasure,” and an Inspirational Personal Brand, is featured in the International Journal of Sport Communication.
