Mark Jones admits Llanelli will be hoping Edinburgh pull off a major shock after being handed the prospect of a daunting last four showdown in France.
The Scarlets saw their worst fears come true at the draw for the Heineken Cup semi-final when they were the last name out of the hat.
And that means that their reward - if they beat Biarritz in the quarter-final at Stradey Park in April - will be a trip to either Murrayfield or Bordeaux later that month.
"It probably could not have been a worse draw for us," said Scarlets and Wales wing Jones.
"The only thing you can ask for at this stage is a home draw but also going somewhere like Toulouse is probably one of the hardest tasks in European rugby.
"If you look at results people would probably say we would prefer to go to Edinburgh as we have already won their this season.
"But I've lost plenty of times in Edinburgh and we're well aware that wherever you go in the semi-final you know you are going to play the best team from their country.
"That should be a good game between them and though Toulouse will be favourites, Edinburgh know they can beat them."
In the other semi-final the winner of Munster-Stade Francais will have home country advantage against either Wasps or Gloucester.
That has laid the path for a Toulouse-Munster final but Jones, who will have recovered from today's knee operation in time for their quarter-final, insists Llanelli will have something to say about that.
"We've got enough experienced players in the squad to be able to go away and know how to wing and the win ay Northampton has given us a lot of confidence.
"But we're still really disappointed not to be at home, not so much for the players but especially for the fans.
"It would have been great for the supporters to play in Wales and create an amazing atmosphere.
"But we have got enough to think about with Biarritz. That has to be the only thing we are thinking about as we discovered to our cost last season that you cannot take anything for granted."
Llanelli have never reached a European final having twice been semi-finalists - in 2000 and 2002 - and lost to Perpignan at home in the last eight last season.
