One day I might tell you who I support but really, for the purposes of matched betting and advantage play, it doesn't matter. The whole point of matched betting is that you don't care about the result, in fact if you do then you've probably done it wrong. Advantage play is slightly different, as using if bets you'll be wanting certain things to happen, but making a profit is the main goal, regardless of how dirty it makes you feel if you have to back and cheer on a team you don't like!
With that in mind though, there are plenty of offers on the Manchester Utd vs Bayern Munich game, and that makes me delighted that they're still in Europe. Long may it continue.
