The bash, the sixth hosted by the travel software provider, will return to Rocks Lane in Barnes, London, on 11 September.

Topdeck Travel and C&M Travel Recruitment have signed up as event sponsors supporting the referees and pitches, while TTG Media returns as media partner.

Dolphin, Topdeck, C&M and TTG will compete alongside teams from across the travel sector, including Travel Nation, Trailfinders, Intrepid Travel, Do Something Different, ATD Travel Services and Exodus Travels.

Jaklien van Melick, Dolphin Dynamics marketing manager, said: “We’re incredibly excited to host this event for the sixth year running and are very grateful for the support of the teams.

“We would like to thank all participants for their generous support and our sponsors TTG Media, Topdeck Travel and C&M Travel Recruitment in particular for their generous donations.”

Brendan Hanlon, head of fundraising and communications at Just a Drop, added: “Over the years, Dolphin Dynamics’ annual five-a-side has raised thousands of pounds for Just a Drop, which goes towards our projects helping people access safe water for the first time.

“It’s still a massive issue that affects millions of people across the world and it’s great that all of the players are doing their bit.”

Trailfinders lifted the prestigious trophy in 2017, with Exodus Travels taking the title last year.

Team TTG Media will be looking to build on their dramatically improved performance during last year’s tournament, when they scored two goals.

Captain Anwar Sohawon said a draw was well within his side’s grasp this year.
