Millers Director Dino Maccio, who was born near Rome has family supporting them and will be helping to bring them to Millmoor.
If the bid is successful, it will be a major financial boost for the cash-strapped club as the ground would expected to be near full as it would be the first time for years the club has had an european team on the hallowed turf.
Roma's star player, Francesco Totti is currently injured but is hoped to be fit for the World Cup.
Meanwhile the Millers are in talks with Manchester United regarding another Pre-Season game, and United have said there is a possibility of sending a side over to Millmoor.
