Director of rugby Les Kiss said Ulster had delivered a complete performance in routing four times European Champions Toulouse 38-0 at Kingspan Stadium on Friday night.
The victory secured five match points and put the Irish Province right back in the mix for qualification from Pool One as they moved from bottom to second place.
Tries from Nick Williams, Andrew Trimble, Luke Marshall, Stuart McCloskey and Chris Henry, with four conversions and a penalty from Paddy Jackson plus a conversion from replacement outhalf Ian Humphreys registered Ulster’s fourth win in five games against the formidable French side in Belfast.
Having been humiliated three weeks ago at the same venue by Saracens - who left with five match points - Kiss was obviously delighted to get the Euro campaign back on track, but warned of a backlash in France next week when they go to Toulouse.
“They are a class outfit and our boys certainly were brilliant at keeping them to nil, but we know next week is going to be a different story and we have to be geared up for that.
“We have to enjoy that victory tonight but we have to be ready for what will be a massive backlash from them. We probably hurt them and they will be wounded and come out fighting.”
In terms of reigniting their chances in the qualification stakes, Kiss added: “My belief before this game was we were only one fixture into the group (due to the postponement of the Oyonnax game), there was not really a true form line thought the pool and to do that we needed to get a win tonight,” he added.
“I do think Saracens are still in the box seat they can place themselves well after at the end of the back-to-back games.
“At the end of round round four, they will probably still be in the box seat. We will be a the end of round three and it will be important to get some points out of it next week.
“We have put pressure on the others to do what they have to do. Toulouse will want to try and get back at Saracens and back at us next week, but if we can do the job next week and then Oyonnax away, the away game to Saracens becomes a very big week.”
