Not late for the fact that its still a world cup which many people around the world watch the league even though its quite late but this is still good addition if we talk about increasing awareness about their casino existence. If they really plan to do this then maybe they should execute this plan because for sure they can succeed with that especially if their logo will be attached on some teams jersey or even promoted by famous individual for sure their fans will look at it or even speculators who watch the game.
They might have some plans to have sponsorship deals with some company in the next one or join hands with some league to have promotion on big level as we have seen from some other casinos also but it depends on the team in which direction they want to have promotion going on so leave it to them.
