Andrew Trimble has warned Ulster can "expect a backlash" from Toulouse when the teams renew European Champions Cup battle in the south of France this weekend.
Ulster sensationally demolished the Top 14 giants 38-0 at Kingspan Stadium on Friday night but their try-scoring wing believes it will be a completely different game at the Stade Ernest Wallon on Sunday.
The 31-year-old was there in 2007 when Toulouse beat Ulster handily after suffering a 30-3 loss in Belfast earlier in the winter and the province have more recent memories of disappointment in double-headers after they failed to back up an impressive away win at Northampton in 2012 when the English side visited a week later.
"The Toulouse we saw on Friday night is not the one we are going to see next week," he contended.
"We have seen it before when we gave them a hiding - they are a completely different side when they are at home.
"We have got to go over there and produce a massive performance. We have to be clever, we have to be ambitious and they will play a different game plan at home.
"We'll expect a backlash.
"They won't have been happy with 38-0 and these back to back games, every year in this competition, they are completely different."
After defeats for Leinster and Munster over the weekend, Ulster are suddenly the province best placed to make a run at the European quarter-finals.
