Scottish Football Association chief executive David Taylor has promised the Scotland-Ireland Euro 2008 bid will be built on a clean campaign.
Taylor is determined to avoid the kind of dirty tricks tactics that have shrouded bids for other sporting events in recent years.
Taylor said: "It's important we fight a clean campaign. Scotland has a credibility which UEFA knows about - based on integrity - and we don't mess about with these issues.
"But there is no evidence this campaign is of that nature. Tactics have been discussed at length so we know what sort of campaign we are running. We will try to make sure we get the right approach".
Taylor and the bid team are refusing to rule Croke Park out of the running as one of the eight stadiums needed to host the event.
The GAA denies non-Gaelic sports the chance to use the 78,000 stadium but Taylor is cautiously optimistic the stance will be altered in time for the 2008 bid after the GAA agreed to host the UEFA delegation on their arrival for inspection of the bid.
Taylor said: "I think that the important thing is that Croke Park were happy to host the delegation . . . they see the bid as being for the country of Ireland and know the benefits from that".
