ERC can confirm that the Federation Française de Rugby (FFR) has withdrawn its application to host the 2014 Heineken Cup and Amlin Challenge Cup finals, due to the ongoing uncertainty regarding the availability of the Stade de France.
For a team who have been crowned English Champions four times in the last eight years, to be currently sitting seventh in the Aviva Premiership, some 13 points adrift of a play-off spot, isn't deemed good enough.
And Van Gisbergen, who owns a trio of European medals courtesy of two Heineken Cups and one Challenge Cup, admits that the quarter-final encounter at Quins now has to be their saving grace this season.
"This is our season. That's where we're at. It's a must win and nothing else will be good enough," said van Gisbergen.
"This is to save our season, basically. It's all on the line. It's going to be massive."
Defeat to London Irish last weekend was Wasps' ninth in their last 11 fixtures in all competitions.
Losing has become a worrying trend for a side who for so long seemed to find a winning way whenever it really mattered.
But while van Gisbergen insists the barren run has nothing to do with effort, commitment or camaraderie, the New Zealand-born England international can't quite put his finger on where things have been going wrong,
"It's not a lack effort, it's not a lack of team spirit, everyone's doing their best and everyone's giving 110 per cent," added van Gisbergen.
"It's just that, for whatever reason, at the moment it's just not clicking. It's horrible and I think it's harder for the players than the fans and it's horrible for them to have to watch that.
"We had a great start against London Irish. The flow was going our way, we were pretty clinical and things were going well. But the penalties killed us.
"We've played Quins three times this season and I've played them lots of times before so we know what they're all about. Our desire will be there, just like it always has in the last few weeks, we've just got to be more clinical.
"If we can get a win this weekend, and go on to bigger and better things, that would be fantastic."
With long-term injuries to key players such as the now retired Phil Vickery, club captain Tom Rees, flying wing Tom Varndell and, most recently, Saxons centre Dom Waldouck, Wasps can claim to have been hard done by on that front so far this year.
But misfortune in that area has at least given a number of promising youngsters - including highly-regarded wing Christian Wade - the chance to impress and van Gisbergen hopes that will have long-term benefits for a club that is desperate to return to the top of the European tree.
"It's great to see these young guys coming through - that's what the club needs. It's up to them to step up now and keep things going forward.
"Christian's another one of these young guns for the future. He's got a big future ahead of him. He's played a lot of Sevens and performed well on the Sevens circuit. Now it's about that transition into the 15s game.
"I thought he showed a lot of promise at the weekend. He's a good young player and things are looking good for him.
"If I can offer him anything at the back or try and settle his nerves a little bit and give him the confidence he need, that's great.
"We've got these young guys coming up through the ranks and, hopefully, in a few years' time they'll be the core of the side and will bring that success back to Wasps, which is what we all strive for."
