The value of the deal has not been revealed but it is thought to be worth millions of dollars, according to specialist esports publications.

The agreement covers 55 countries in the Europe, the Middle East and Africa regions and will see the Subway logo feature on the kits of the Guild team.

Subway's logo will be on Guild Esports' branded content, while it will serve as the company's official quick-service restaurant partner under the terms of the deal.

It will also support young gamers on the Guild Esports team.

"We are incredibly proud to partner with Subway, an iconic global brand and the world's largest submarine sandwich franchise," said Guild Esports executive chairman Carleton Curtis.

"This partnership is particularly exciting as we are completely aligned with Subway’s commitment to helping people make better choices.

"It is our shared values that will provide a strong foundation for Subway’s unique relationship with our academy, which provides opportunities and education to the next generation - from career opportunities to health and wellbeing. 

"We look forward to deepening our partnership with Subway for the long term."

Guild Esports revealed last month that it had recorded a pre-tax loss of £2.7 million ($3.7 million/€3.1 million) in the last financial year but claimed it is on track to deliver "significant sponsorship revenues" with Beckham's help.

Beckham, capped 115 times by England and who enjoyed successful spells with Manchester United, Real Madrid, AC Milan and Paris Saint-Germain, made a five-year commitment to act as Guild’s brand ambassador.
