bwin is perhaps the largest sportsbook in the world and they a history of spending big money to sponsor football clubs in Europe.
They recently signed on as the betting sponsor of Manchester United which should give bwin access to a loyal fan base that probably likes to bet on football.
bwin is currently the shirt sponsor of Real Madrid and a betting partner with Bayern Munich.
bwin used to be the shirt sponsor of AC Milan and previously failed to secure a bid to become the betting partner of FC Barcelona.
Manchester United has one of the largest followings of fans around the world so this deal gives bwin easier access to them.
For affiliates this could mean better conversions but it also means dealing with the bewinners affiliate program which for small affiliates is not friendly at all since they frequently close accounts based on performance. For larger affiliates this is probably welcome news.
There are other football clubs in England that have either shirt sponsors with online gambling sites or have betting partners.
Just to name a few brands that have made appearances on English Premier League jerseys: Bodog, 32red, Sportingbet and Mansion.
This news also follows the announcement of signing forward Robin Van Persie to a 4 year contract that could help Man U win a title they essentially lost to Manchester City last season.
