The Balkan nation have not qualified for a major finals in seven attempts since becoming an independent state back and Papac, who has not played at international level since 2006, is looking forward to the meetings with Luxembourg and France.
Bosnia currently sit second on the Group D table and a win in Sarajevo over bottom-placed Luxembourg will ensure qualification and set up a top-of-the-table clash with France in Paris on Tuesday which Papac knows will be a massive encounter for those back home.
"It would be the first time we had ever qualified for a major finals - but we are a young country," he told the Sunday Mail.
"We've come close a couple of times before, taking it all the way down to one game. The last world cup qualification we lost to Portugal in the play-offs.
"The one before that we went down to the last game in the group as well, and for Euro 2004 we drew our last game with Denmark when a win would have seen us qualify.
"It's always making the last step - maybe now is the time to do it. We're in a good position in the group, one point behind France with two to play and our last game against them.
"If everything goes to plan against Luxembourg on Friday, then it goes down to the last game in Paris. That's a hard game but it's good to be in that position.
"We'll not be feeling the pressure too much. The fans, the players, everyone wants to get to a big tournament but it's not an easy thing to do.
"There will be more pressure on France. If they don't go to a tournament like this it is seen as a disaster for them."
