The Celtic and Liverpool 'Dublin Decider' played at the Aviva during the summer was a big success in terms of attendance. So imagine what the demand would be like if Celtic were to play an actual competitive Champions League qualifier in Ireland.
Speaking to STV, Celtic chief executive, Peter Lawwell, said this was a possibility they had looked into.
The Commonwealth Games are being held in Glasgow next summer and Celtic Park is one of the stadiums being used so it would probably be unusable for Celtic's second round Champions League qualifier and possibly the third round qualifier.
Lawwell said that Scottish rugby's Murrayfield was the most likely venue to be used but that they had also looked at the possibility of playing in Northern England and Ireland.
