Under the deal, EstrelaBet will remain as the team’s master sponsor for the next three years, with is branding to continue to appear on the back of players’ shirts.
The operator will also work with the club on a range of other fan-focused initiatives over the course of the partnership.
EstrelaBet began its partnership with the club last year, at a time when it also entered into a deal with another Série A team in Athletico Paranaense.
“EstrelaBet’s support brings news that our fans will like, reinforcing the brand’s confidence in the history and greatness of the club,” Internacional president Alessandro Barcellos said.
EstrelaBet’s head of sponsorships Rafael Zanette added: “Renewing this link was the natural path because it is much more than a sponsorship contract, it is a true partnership, which yields great results. We have no doubt that it will be a huge success.”
The 2023 Série A is due to kick off on 15 April.
