Dublin will stage at least 10 games at the 2030 World Cup if the UK and Ireland bid is succssful.
And Croke Park could host the opening match and a quarter-final if the GAA decides to open its doors for the 48-team tournament.
The final decision on who hosts the 2030 finals will be made in 2024, with FIFA formally opening the process next year.
For the bid to be successful, Dublin must have two stadia with a minimum 40,000 capacity. At 18,500, Windsor Park in Belfast does not meet World Cup criteria.
Stadia hosting quarter-finals must have a minimum of 60,000 seats and 80,000 for the opening ceremony and final.
Speaking in 2019, former interim FAI boss Noel Mooney said: “We have an excellent relationship with the GAA.
“I think - and I would hope - they would look favourably upon requests to host a World Cup match in Croke Park.
“Certainly in our thinking, the stadiums you would be looking at are Aviva Stadium and Croke Park, they are the two natural homes for World Cup matches.
“It depends on the amount of matches you get. The way it's laid out at the moment is that the Republic of Ireland would host quite a number of matches.
“While that's not finalised, you couldn't host them all in the Aviva Stadium so in an ideal scenario, you would have two stadiums.
“Croke Park is a magnificent venue and we would all love to see World Cup matches played in Croke Park because it would mean a lot to Irish people.
“It would be very attractive to the bid itself for lots of reasons.”
Hosting World Cup games at Croke Park in the summer would mean a clash with GAA championship matches.
But Mooney said: “You could find solutions. They even managed to host the World Cup in Qatar. If the desire is there, it would be a huge national interest.”
Quizzed on the amount of World Cup games being earmarked for Dublin, Mooney said: “You could be looking at double figures.
“In that instance you would definitely need two stadia. Without having any agreements in place, hosting matches in Croke Park would be really attractive for the bid."
Taoiseach Micheal Martin today said the Irish Government will do everything it can to support the bid.
Mr Martin said: "I think it was very interesting and obviously it's very early days but we're very happy to cooperate with the UK and indeed all the Football Associations involved,
"The whole idea of Ireland as a location for major events is something successive Governments have been pushing for now and this falls into that,
"It's early days but we'll certainly do whatever we can to add value to that proposition because I think sports fans will be particularly happy with that and it would be something to look forward to."
The 2022 World Cup will take place in Qatar next year, while the 2026 tournament is to be held in the United States, Canada and Mexico.
