ERC can confirm that the Federation Française de Rugby (FFR) has withdrawn its application to host the 2014 Heineken Cup and Amlin Challenge Cup finals, due to the ongoing uncertainty regarding the availability of the Stade de France.
Even though Bath had not lost at home for more than a year until the Blues took that record last Friday, Roberts knows that going to Paris to face Stade Francais will be quite a step up again.
"The next two weeks are probably the biggest games that Cardiff Blues have had in their history," said the 21-year-old.
"The Heineken Cup group we have got we are really confident we can qualify this year and really move things forward as a region, so these next two weeks are huge for everyone at the club."
It was feared Roberts would miss most of the season after injuring his should in the defeat at Leicester, but he is back in action.
"Up in Leicester I tried to ankle tap the winger and fell awkwardly. I've had a scan and it is not the best unfortunately," he admitted.
"It is one of those injuries that if you strengthen your shoulder enough and you are not in pain then you can play on - people play through their whole careers with injuries like this, hopefully I will continue like that over the whole season and touch wood it will not get injured again.
"I am just delighted to be playing, I played seven of the first eight on the wing and I was over the moon. I think my long term future is at full back but Ben Blair is a great player and I am sure he will be involved against Stade.
"But I am only 21 and I learn a lot from him, he has been brilliant."
