John O'Shea and Kevin Doyle are back in the Ireland team for tomorrow night's Euro 2012 play-off second leg against Estonia in Lansdowne Road.
Stephen Kelly at right back and Jon Walters in attack are the players that make way for the returning duo.
O'Shea comes back into the side following a hamstring injury, while Doyle returns from suspension to partner Robbie Keane in the Irish attack.
In a third change to the starting team from the first-leg encounter in Tallinn, Stephen Hunt takes Aiden McGeady's place on the wing, but Giovanni Trapattoni has indicated that Spartak Moscow man McGeady will play the second half of the game.
The Irish management team also confirmed that LA Galaxy requested Keane return to the United States following Ireland's 4-0 away win in A. Le Coq Arena. However, the team's captain has chosen to remain in international camp for the second leg.
LA Galaxy play Houston Dynamo in the final of the MLS Cup on Sunday, which explains the California team's desire to get the Ireland international back to the States.
Ireland captain Robbie Keane believes their Euro 2012 play-off tie against Estonia is all but over after their 4-0 first-leg win.
Keane scored twice as his team thrashed their nine-man hosts in Tallinn.
"It is a great result. This game should be over now and if we don't qualify we'll be devastated," said Keane ahead of Tuesday's return leg in Dublin.
"We deserve to go through because of the way we have played in the campaign. There is confidence in the squad."
Estonia will be missing missing first-choice keeper Sergei Pareiko and central defenders Raio Piiroja and Andrei Stepanov through suspension for Tuesday's return leg.
But Giovanni Trapattoni was keen to stress that his side must keep their focus.
"The cat is in the sack, but the sack is not closed," said the 72-year-old. "The cat is in it, but it's open - and it's a wild cat.
"But we have to have respect for our opponents for what they have achieved in this qualification campaign.
"At this moment, we are near qualifying at 4-0. But I repeat the same sentence: don't jump the gun."
Keane, who has now scored 55 international goals, was full of praise for his fellow goalscorers after Keith Andrews opened the scoring and Jonathan Walters notched his first international goal.
"Jonathan Walters is brilliant," added Keane. "He's a handful and he deserved to score. Keith was superb from the start and he drove us on from midfield."
Andrews admitted the result had come as a bit of a shock.
"It hasn't sunk in yet. It's hard to believe we have come here and won 4-0," said the Ipswich Town midfielder.
"I thought we played very well, harried them and fortunately got the result.
"If we keep a clean sheet it will be a fantastic night on Tuesday. Over the past few years this group has really come together."
Robbie Keane has insisted that Ireland will be going all out for victory in tonight's Euro 2012 play-off clash against Estonia.
Giovanni Trapattoni's 'Boys In Green' will start in Tallinn knowing that a draw would be a decent result to take back to the Aviva Stadium on Tuesday evening. However, Keane is adamant that a win will be the only thing on their minds as they attempt to take a major stride towards qualification for next summer's Euro finals.
He said: "Listen, as players, you don't go into a game thinking you are going to draw, it's impossible to do it. You go into every game thinking you are going to win it, so we are going into this game thinking that we can win it because there is no reason why we can't."
He added: "We have the players to do it and we have the mentality to do it, so there's no reason why we can't do it.
"We go into every game with the same mentality, that we can win this and we can score goals."
Ireland's recent run of form backs up Keane's claims - they are unbeaten in nine games and have conceded just one goal in the process.
Keane is confident that is evidence of the improvement they have made under Trapattoni's guidance in the last three and a half years or so.
He said: "You have seen over the years since the manager has come in, we have grown as a team, we have got better with each game and that reflects in our performances and the fact that we haven't lost too many games.
"Of course, we are a better team. The players are getting more experienced and able to handle different situations, so we are certainly a better team than we were a couple of years ago."
Ireland striker Jon Walters says he won't be afraid to mix it up with Estonia's defenders if required by Giovanni Trapattoni during the Euro play-off's.
The Stoke City player is vying for a starting birth with Simon Cox, for Kevin Doyle's place and is adamant that he will play whatever role he is asked to in Friday's away encounter.
Walters said: "I am not the sort of player to shirk out of anything, I'll go wholeheartedly into anything so if that's putting myself about or doing whatever needs to be done, I'll do that.
"I have the scars on my head and eyebrows to prove that. I'll get involved and get mixed up in whatever needs to be done."
28-year-old Walters played just over 10 minutes of the last group game but may have done enough to pip Simon Cox for a starting place in Tallinn.
He is also Stoke's joint top scorer this season with five goals in 21 appearances, compared to Cox's one goal in six games for West Brom.
With Robbie Keane having come through three games with LA Galaxy after his injury, Walters is hoping that he gets the nod to partner the Irish captain in attack. He says that his ability to play with different types of strike partner may give him the edge.
"I've played with so many different strikers over the past few years, five or six in the past year while I've been at Stoke. I think that adaptability is one of the attributes of my game and playing well with different players and linking up," he said.
"Whatever the manager asks you to do or how to play, you try and if it's a different job I am asked to do - whether it's to hold it up or flick it on and behind, I'll try my best to do that.
"[In the last game against Armenia] after about 30 seconds of coming on, Doyler got sent off so that changed what I needed to do. I went up there just to hold up the ball and keep the pressure off our defence for a little while, that was my job and hopefully I did that quite well."
"Obviously, it's only the halfway point after the first game and we've got to concentrate on getting through. but getting a goal away from home is always important and with such a good defensive record, that we have as a team, if we can get a goal it can be enough.
"They've done exactly the same as we've done to get where they are. They're not going to be pushovers and they're not going to be easy. We may not have heard of them so much in world football but you tend to find players from countries like that are technically very good.
"As soon as you underestimate teams you get a kick up the backside. So that's the last thing anyone in the squad will be doing. It's the worst thing you can do."
