Did you watch the game ? Frankfurt took the early lead and could have made it 2-0 shortly after, but Silva was too pathetic. Leverkusen then needed a penalty to make it 1-1. The scoreline looks like quite some beating, but it could easily have gone the other way, like so often in football
Frankfurts odds probably didn't have that much value if any, but so didn't Leverkusens. Don't think they would have won this one way more than 50% of the time. Sometimes the odds are just fair and you should just leave those games alone then, but thats easier said than done
