yes you would have. The 90th minute mark plus whatever added time in each half is the timeframe, normally and almost always that a football game is decided and a bet too, in some rare cases extra time (not added, huge difference) consiting of one or two extra halfs of 15 minutes are played, this may happen, I am sure it will in some game or other, in the knock out stages where there has to be a final winner to advance to the next stage, besides the tie, for a team to go through to the next stage as they are not competing in a round robin group, thus they add an two extra 15 minutes halfs and if there is still a tie after that they go to a penalti shoot out, where the winner is decided amonst who scores more goals in the first five penalti kick outs, thats a single shot to the goalie, if they are still tied after that, each team shoots a single penalti, until one eventually misses a penalti.
Having said all that, almost all bets, consider just the 90th minute period (goes without saying the added time in each half (the rationale of that is that the added time goes towards all the time spent/waisted on substitutions, players injuries etc. etc. its up to the ref to calculate this time and declare it to the fourth ref who pulls out a card showing the added time, that happens because unlike basketball, I dunno about american football, soccer is not an exact time game, there's no stop clock that gets pressed when there's dead time). If they don't they specifically claim that any extra half will also be included, and that very seldom happens.
hope all these help.
