So I've picked Steaua to win at Shalke on Wednesday in the Champions League. Not very likely, as the odds of 9.0 at Vernons suggest, but a close match of 9.8 at Betfair mean we're in business.
£25 on at Vernons
£15 lay at BetFair
Steaua win and it's +£200 at Vernons - £132 at BetFair = +£68
Steaua don't win and it's +£15 at BetFair (- commission)
Everyone's a winner!
COME ON STEAUA!!!
p.s. If you were doing this as a new user you'd have to play through your stake returned if Steaua lost, so you'd probably lose another £1 in that transact
