Lay £9.88 on New England Patriots @ 1.61 = Potential liability of £6.02


Let’s have a look at our potential profit/loss for the possible outcomes…

Patriots win+ £5.71– £6.02£0.31 loss
Any other outcome– £10.00+ £9.68£0.32 loss

So, no matter the outcome, we’ll lose a maximum of £0.32 in qualifying for our £5.00 free bet.

Free bet

Our £5.00 free bet will be credited by 17:00 on Monday 13th September 2021 and will be valid until 09:00 on Tuesday 14th September 2021.

Using straightforward matched betting, we should be able to convert our free bet into 80% cash, so £4.00. If we take into account our maximum qualifying loss of £0.32, this gives us a guaranteed profit of £3.68 on this Betfred offer!
