In the contrary one win from Liverpool will render @OP with a win, all losses from the previous bet recovered.

So @OP, for example you intend to bet $5 in a 10-match series, you need to have at least a balance of $2560 to cover all the matches. It is quite expensive but more or less there is a good chance that you will be in profit assuming you have chosen a pretty tough team to beat.
Are you sure about that bankroll?
What happens if the favorite fails to win just 3 times while at 1.2?
So, first thing is that if you bet 5$ you will win only 1$ but lets get over that, let's say you have lost a 2.0 bet of $5.
Next match is at 1.2 so in order to recover the $5 and win $ 5, you need to bet $50!
Next match, they are still favorites at 1.25 for example, in order to get back 55 and win 5, you need to place 240!
Third, 1.25 odds, you need to get back 300, your bet must be $1200!
With just
2 losses at 1.20 and 1.25 you needed $1560 in bankroll. if the third one was also a loss, even if your next bet would be at odds of 2.0 you would need 3000 in bankroll to win $5 a week.
