You can get these pre-match bets on either as singles for over 3.5 goals bets and doubles or trebles with under 3.5 goals since the latter has very low odds.

Over 3.5 goals are very profitable and the odds go to as high as 10, Isn't this marvelous?

The idea is to get on every bet with uniform stakes for a better bankroll; uneven stakes can either boost or sweep dry your bankroll, so discipline is key here.
