Double Up Strategy

Keep betting on Evens (1/1) and if you lose, double your stake next time. You will eventually come out winning if you can hold your nerve on the double-up

Persevere with doubling your stake on odds around evens and eventually come out winning.

For example:

1. Sunderland AFC - Fulham FC . . . 2.10 - 3.30 - 3.40

If you put €1 on Sunderland to win, and they lose....

2. Simply next week put €2 on another 1/1 outcome:

Sunderland - Arsenal . . . 2.20 - 3.20 - 3.25

Sunderland lose again, you're now €3 down....

3. The next week put €4 on another 1/1 outcome:

Chelsea FC - Liverpool FC . . . 2.30 - 3.35 - 2.95

Bingo!, they win and you profit € 9.2, wiping out your current €7 loss, and giving you 24% profit.

You'll eventually win if you can keep doubling your stake.

One drawback - if you go on a losing streak your stake can keep doubling and before you know it you could be sweating it out!, and the percentage winnings get lower. However, hold your nerve and make sure you can afford to keep doubling and you will win.
Of course 2.2€ profit doesn't seem like a lot, but multiply up the stakes to what you can afford and you'll be making money.
