The Wolves midfielder was a late substitute in the 1-0 defeat in their Group C opener against Slovenia on Sunday which left the north African nation with a mountain to climb to qualify for the knockout stages.
Algeria, making their first FIFA World Cup™ appearance for 24 years, are likely to have to beat England and USA in back-to-back games to progress. Against Slovenia they held the initiative in the early stages but faded in the second half and their hopes of victory disappeared after the sending-off of substitute Abdelkader Ghezzal.
But Guedioura, who signed a three-year contract at Molineux at the end of the season having initially joined on loan from Belgian side Charleroi, insists they can put the disappointment of that defeat behind them.
"It was a disappointing performance because we didn't deserve to lose," he said. "The team showed they could win the match and the draw would have been more fair and what we deserved. What we have to do is say it is finished now and look forward. Now we have two big matches and we have to be focused for England.
"We showed against Slovenia that we can do something. We will see against England. We need to be focused and we need to be confident. Every game now is a fight and we need points against England so that we can get points in this group."
Both teams have seen their goalkeepers come in for criticism for mistakes which have proved expensive. Robert Green's failure to hold on to Clint Dempsey's long-range shot ensured USA escaped with a 1-1 draw from the opening Group C encounter while Faouzi Chaouchi's inability to deal with Robert Koren's tame strike led to the defeat against Slovenia.
Algeria coach Rabah Saadane has given his goalkeeper his full backing but England counterpart Fabio Capello has been less forthcoming on Green's position. It has led to much conjecture about who will line-up in goal at the Green Point Stadium in three days' time but Guedioura would not be drawn into the debate.
When asked whether he thought both teams would change their keepers he said: "I don't know, I'm not the coach. We saw the England goalkeeper making a mistake so it is not his (Chaouchi's) fault. I am disappointed for him.
"Everyone makes a mistake in football: sometimes it's the goalkeeper, sometimes it's me, sometimes another player."
