Soper believes a quick recovery after Sunday’s game means Ulster cannot afford the loss, but they must also try to correct some of the mistakes they made in France.
Another tough test at Kingspan Stadium on Saturday. That’s because the Bordeaux team took second place in France’s top 14.
“We went out on the pitch today so we can’t obsess too much about getting up and having to go again,” he added.
“It’s a young group and we’re always learning, but we have to start performing.”
Soper will be hoping that despite the lengthy injury list, Ulster can respond to the heavy defeat by Toulouse and produce a performance they can be proud of on home soil.
“At this time of the year there is always pressure and expectation about Ulster playing at home, but that is the privilege of what we do. We will perform on Saturday and turn up expecting a result,” he said.
“No matter what the structure of Europe is, if you think you have any chance of progressing, the home games are usually the games you have to win.”
