I don't see the reasoning on betting a team to advance pre-match, If you like Brazil for example, bet the PK at the same odds and if they win the game in regulation , done deal . If it's tied and goes to extra time , you can rebet on your team to advance after being able to watch the play for 90' , see who is getting the chances, see if the refs are fair, etc. And if your team loses in regulation , you would have lost either way .
What you don't want to do is see your team dodging bullets for 90+ minutes, with your money tied up, and they lose in ET
