The Premier League is turning more and more to betting companies for sponsorship.
These partnerships make sense for both sides since sports betting for many is part of the overall experience of being a fan of a club.
West Ham agreed a new shirt sponsorship just this season with Betway.
The agreement, believed to be worth in excess of £10million per annum, represents a significant upgrade on the £6m that the Hammers earned on their previous deal with the bookmakers.
West Brom also boast a casino sponsor, which was secured late, last season. The agreement was a record commercial deal for the Club.
