Goalkeeper Green's blunder gifted the United States an equaliser in last weekend's 1-1 draw in Rustenburg. He has been the topic of constant speculation this week as to whether he will be given another chance by Capello or whether he will be replaced by Joe Hart or David James.
But Capello will not break with his tradition of informing his players whether they are playing until shortly before they board the team bus for a game. He said: "I have decided but we have to wait until tomorrow. I haven't told the goalkeeper who is playing.
"As always, they will find out on the the day of the game - never the day before. I think when I chose Green it was a good moment for him, after the game he played against Mexico. He played very well in that first half.
He added: "I think all the players make mistakes - the forwards, the keeper, the defence. But I have to choose the value of different players and it's not about their mistakes."
The other area in which Capello admitted yesterday he was considering a change was upfront, with Emile Heskey and Jermain Defoe vying to partner Wayne Rooney. Capello is pleased with the form of Heskey but may opt for a different style against Algeria which could lead to Defoe being called up.
He said: "I think Heskey and Rooney played very well but I can change the style of the forward. I think Heskey is a very important player in terms of movement at this moment but Defoe is also important, like the other players. I have to choose."
Capello believes there was not too much wrong to concern himself with in terms of the performance against USA. He said: "I was happy after the game against the USA for everything I saw during the game. Only the result I was not happy about. Only this.
"But for all the teams who played the first game, it was not easy. The pressure of the first game is higher than in other games. We didn't score the goals. We created a lot of chances. I want to see no mistakes, only this, because I think that when you create so many chances it's possible the team will score them this time."
Capello is adamant he will not underestimate Algeria as England look to move closer to the last 16 by securing three points. He said: "I respect the team. They score a lot from counter-attacks and set-pieces. I've learned a lot in this period and seen all the games in the World Cup and no games are easy. It will be a big mistake to think this game would be easy."
