Declan Rice has not been named in the Ireland squad for the upcoming games against Wales and Poland.
The West Ham player made his international debut against Turkey earlier this year but is yet to play for Ireland in a competitive international. He also played in friendlies against France and USA. That means he can still switch his international allegiance.
Speaking at a press conference on Monday, Martin O'Neill said that Rice is considering his international future. He added that there has been an approach from the English FA.
"He is still deliberating," said O'Neill.
He is a young man. England have spoken to him. He is taking time to make his mind up. He has done brilliantly for us. I'm giving him a little bit of time.
I wouldn't be exaggerating to say Declan has loved it with us. After the Turkey game his father was there and it was a joyous moment for them.
We have done everything we can. He has been welcomed by the squad, the fans. He is taking time and I am respecting that.
James McCarthy, Robbie Brady, Scott Hogan and Sean Maguire were all ruled out due to injury.
Included for the first time in an Ireland senior squad is Sean McDermott. The 25-year-old goalkeeper, who qualifies for Ireland through his Donegal-born father, plays for Kristiansund BK in Norway's Eliteseruen. He has previously represented Ireland up to U21 level.
Preston striker Callum Robinson has also been named. Robinson played for an Ireland XI against Celtic in Scott Brown's testimonial earlier this year. He has since received international clearance.
"His paperwork has gone through to represent us competitively," said O'Neill. "I saw him recently against Norwich. He is a nice footballer. I will be encouraging him to take players on. This is what I want Robinson to do."
Ireland play Wales in the first game of the new Nations League on September 6th in Cardiff and then Poland in a friendly in Wroclaw on September 11th.
