Please don't just read the title and hear me out as I couldn't think of anything better and shorter at the same time.

I have had a debate with someone about the martingale system which we both know it's failure but with adaptation and low bets low revenues, compared to simply straight betting for the favorite. The talk was about choosing top tier team from each football league and keep on betting in a side by side experiment for the entire championship.
Luckily for me it seems like the statistics are available , so I want to give it a try on past records for some like 5 teams, a straight bet on win, a bet on win or draw, and a martingale system with a cut loss at 5.

Do you think any of the strategies would have worked this season?
Which teams should I consider? My choice were Inter, Arsenal, Liverpool, Chelsea, Bayern, Real, Barcelona and PSG but those are way too many!
