"I should imagine I will play in a more forward and attacking role and that suits me," said the Liverpool midfielder.
"It's great to have Gareth back and available, hopefully he'll provide protection for the two centre-halves."
Head coach Fabio Capello has broken with tradition to confirm that Barry will start against Algeria after shaking off an ankle injury but has kept the rest of his plans under wraps.
Reports claim that he will stick with Robert Green despite the goalkeeper's costly error against the US.
Jermain Defoe could partner Wayne Rooney in attack in place of Emile Heskey.
"I have made up my mind, but I will announce the team on Friday and the players will find out on Friday," said Capello when asked about his potential line-up for the game in Cape Town.
Meanwhile, Capello is also keen to dismiss suggestions that Algeria are the weakest team in the group following their opening defeat to Slovenia.
"They have scored a lot of goals. Algeria are dangerous at free-kicks and corners. Also on counter-attack they play very well," he explained.
"I saw all the games that have been played. Not one game is easy. It will be a big mistake to think this game will be easy."
