Young looking for one last effort
Dai Young has promised Wasps will empty the tanks as they seek to claim a seat among Europe's elite in the final match of their season.
The London club head to the Stade Jean-Bouin protecting a narrow 30-29 victory from the home leg of their European Rugby Champions Cup play-off against Stade Francais.
The winners over the two games will claim the 20th and final place in the successor to the Heineken Cup.
A six-day turnaround between matches has posed challenges to both clubs, but Young insists Wasps have the desire to seize the prize on offer.
"It's been a short turn around and that can be a mental thing, but if you can't get up for these types of games and if you can't carry some bumps and bruises, you ask questions," the director of rugby said.
"But I never have to ask questions about this group because they want it just as much as anyone else.
"I've had to look after them this week and we haven't changed much.
"We caused Stade lots of problems in the first game. A one-point win out there will be enough.
"It's a big challenge, but one we're looking forward to and we'll leave nothing in the dressing room."
Young has named Guy Thompson at number eight in place of Nathan Hughes, who has returned to Fiji for his wedding. The ceremony had been planned and booked before he joined the club.
Stade are strengthened by the return of Italy captain Sergio Parisse from injury.
