You need to choose only ONE team and follow it through out the season and always bet X on it. For example you choose Bordeaux, bet first game X @ 3.20, stake £10 ... if the bet is lost, the next bet will be Bordeaux X @ 3.20 for £15 ... and so on, raising the stakes by 50%. I guarantee that by the end of the season you'll have loads of profit.
Hope you like it, it has done wonders for me.
[Editor's remark: as always be careful with progression systems. A losing streak could erase your betting bank!]
