Manchester United have expressed an interest in hosting some of Ireland's home internationals.
The club has said that they would be 'delighted' to hold some of the games in Manchester, and stated that their officials have been in 'informal' contact with FAI representatives in regard to the matter.
In a statement the club said: ""We have had informal conversations with the FAI and, subject to approval from the appropriate bodies, we would be delighted to host some games at Old Trafford."
The FAI has reportedly denied that any such talks were held.
Earlier, Celtic told the Republic they may also be able to use Parkhead for their World Cup qualifying matches.
A Celtic spokesman told the Scottish Sun: "We have already made it clear to the FAI that we'd be delighted to discuss the possibility of hosting future Irish international matches at Celtic Park."
Anfield, home of Liverpool football club and Manchester United's Old Trafford have also been mentioned as possible venues for the Republic's 'home' games.
Plans to revamp Lansdowne Road have yet to get off the ground and that could mean the Football Association of Ireland looking elsewhere to play their home games against France, Switzerland, Cyprus, Israel and the Faroe Islands.
Both the FAI and IRFU have presented proposals to the Government on redeveloping Lansdowne Road into a 50,000-seater stadium.
The Government, however, has yet to decide whether or not to provide funds for the estimated €250m plan.
