This is unusual. When the Republic of Ireland reached this stage of the qualification process for a major tournament in the past, they were normally billed as the plucky underdogs. But not in Tallinn. In this Estonian football pond, the Irish are the big fish.
It is a sensation which is taking a bit of getting used to for the 3,000 or so travelling supporters.
Yes, I know the FAI received just 1,400 tickets for the game. But that has never stopped ticketless Irish fans from making the journey in the past. So, why start now?
Along the cobbled streets of this charming medieval city, the first Irish flag we notice just happens to be draped over the doorway of what is, to all intents and purposes, a strip club. Opportunistic marketing? Don't they realise the fans are here purely for the football?

If it is true that France and Germany have been considering new economic proposals this week aimed at reducing the size of the Eurozone, Estonia could have reason to be a little jittery. It joined the Euro in January of this year. Last in first out?
Yet football is clearly the new currency on an upward curve here.
This is new territory for Estonia. They have never qualified for the finals of a major football tournament. But having shown Northern Ireland the qualification exit door in September, the Baltic state genuinely fancies its chances of repeating the feat against another Irish football team.
Renee Iliste would certainly convince you anyway. He runs a medieval market stall near Tallinn's Town Hall square. But a glance at what he is wearing suggests Renee would look equally at home on the set of a Robin Hood film.

"The times have changed," he says triumphantly. "We are getting famous around the world for our football. I will be dancing everywhere to celebrate if we win. We love the football."
If he is wearing the same outfit, we may have to come back with a camera to see that.
But there is confidence amongst the visiting support too. Seamus Given, who we bump into, is one of boys in green with a ticket. Mind you, it would be a major surprise if he did not have one seeing as his son Shay is in goal on Friday evening.
"Is he (Shay) nervous?"
"Not really no. He is too professional to be nervous. As they say back home, he is too long in the tooth now to get nervous. He just loves playing."
Several members of the current Republic team were not even born the last time the Republic of Ireland qualified for the finals of the European Championship [Germany 1988]. Given senior believes the time has come to do something about that.
"We will not accept a draw tomorrow. We are going all out for the win," added Given Sr.
And who are we to argue with Dad?
