Bosnia international goalkeeper Asmir Begovic insists there is everything to play for against Portugal in their Euro 2012 play-off.
Portugal only need to win in Lisbon on Tuesday night to book their place in next summer's tournament in Poland and Ukraine following a goalless first leg on Friday.
Begovic knows some fans are not optimistic the nation will be able to secure the required result away from home, although he believes nothing has been lost.
The Stoke City shot-stopper is calling on his team-mates to play with their heads in Portugal and that is it not crucial to attack from the off, stating all the pressure will be on the hosts.
Moment of truth
"I can see that there are fans who aren't optimistic, but I'm sure that nothing was lost in Zenica," he told SportSport.
"There are still 90 minutes to play. We can still achieve our goal. In Lisbon we are playing for everything.
"It's the moment of truth. It won't be easy. Portugal will be better at home but what is most important is that we can score.
"If we repeat our game against France in Paris, everything will be possible. But we'll have to play smart.
"We can't just attack from the first minute. We have to play with our heads.
"Portugal also have to score and they'll be nervous. Even more so if they don't score quickly. And the more nervous they become the greater our chances will be."
