The Leeds United midfielder is likely to partner Stoke City midfielder Glenn Whelan in midfield with Ireland assistant coach Marco Tardelli hailing his agressive style
The 29-year-old midfielder, who has 14 caps for the Boys in Green, was the preferred partner to Stoke City midfielder Glenn Whelan during pre-match training games in Dublin.
And Trapattoni's assistant coach Marco Tardelli has suggested that Green possesses an 'aggressive' style of play that will be more suited to countering the threat of Swedish captain Zlatan Ibrahimovic.
"Paul Green is a player who is more aggressive in the midfield and McCarthy is a player who is skilful and good with his distribution," Tardelli told reporters. "They are different players, but some times it's possible to change some things, to play Green or McCarthy."
He continued: "Aggression is the first thing for us. Because if we are without aggression, it's not good for us facing Sweden.
"Ibrahimovic plays sometimes now in midfield because he drops back to receive the ball. We need to pay attention during this situation," added the Italian.
Sunderland defender John O'Shea looks set to continue his defensive partnership with Aston Villa centre back Ciaran Clark, while James McClean and Robbie Brady are expected to start on the wings, with Shane Long partnering Robbie Keane in attack.
Meanwhile, Tardelli has also indicated his belief that Ireland's performance will not be affected by the roof closure at the Friends Arena.
The Swedish Football Association wants the roof to remain closed in order to maintain the best possible conditions for football - an opinion shared by Fifa - but Ireland boss Giovanni Trapattoni suggested that it would be 'too loud' if the roof was closed.
"We are very strong and it makes no difference to us whether we play with the roof closed or not," said Tardelli. "For me it's no problem but I don't know about the players."
"Fifa decide. Everything in football is decided by Fifa and Uefa," he added.
