Soper believes that the quick turnaround after playing on Sunday means that Ulster can ill-afford to dwell on the loss, but they must also try and rectify some mistakes made in France.
It is another difficult test at the Kingspan Stadium on Saturday as they welcome a Bordeaux side that are second in France’s Top 14.
“We’ve been out on the pitch today so you can’t dwell too much on things you have to get up and go again,” he added.
“It’s a young group and they’re learning all the time, but we need to start putting in performances.”
He does hope that despite a lengthy injury list, Ulster can respond to the emphatic Toulouse defeat and put on a performance to be proud of on home soil.
“There’s always pressure and expectation on Ulster playing at home this time of year, but that’s a privilege of what we do, and we will be turning up on Saturday expecting to perform and get a result.
“Whatever structure there has been in Europe, a home game has usually been a must-win if you think you have a chance of progressing.”
