Watford have secured a new sponsorship deal that will earn the club up to £20million.

The shirt sponsorship agreement is set to run for the next three years and will be with sports betting website Sportsbet.io.

The betting site will take over as the club's front shirt sponsor at the start of the 2019/20 Premier League season.

It is the largest deal for Watford, while it is a significant coup for Sportsbet.io, which is known for its sports betting options related to cryptocurrency.

Spencer Field, Global Strategy & Partnerships Director of Watford FC, said: "This is an important year for the club as we aim to improve on a fantastic season both on and off the pitch in 2018/19.

"Our desire to increase our global reach while continuing to make our fans proud by doing things differently in the Watford way is fully supported by Sportsbet.io

"We are thrilled to have found a partner that matches our ethos by looking to disrupt the betting industry and offer their customers a fun, fast and fair experience."
