The Ireland head coach would go on to admit there was pure relief mixed in among his emotions after Johnny Sexton's handsome last-gasp drop goal secured a 15-13 win for Ireland in Paris, but there was delight too.
And Brunel is sure that Jalibert, who says he wants to emulate England's Andy Farrell, will have no problem dealing the intensity the Irish will no doubt bring to the Stade de France cauldron.
Les Bleus, who have not won in their last seven games, lost teenage sensation Matthieu Jalibert after the flyhalf suffered a knee injury in the first half.
Leinster lock James Ryan dislodged Ireland mainstay Devin Toner to make just his second test start on Saturday against France in Six Nations rugby. "We hope with the referee we've got that it won't even enter into the fray", added the 52-year-old New Zealander.
"The lads' legs were out and I don't think we could have gone another couple of phases so just got there in the end".
The upshot was that France sent Maxime Machenaud, a renowned kicker, back into the fray, a move which also ensured they did not have to play the remainder of the match without a specialist scrum-half.
He will make his global debut at Stade de France only three months after starting his first Top 14 match with Bordeaux Beglés.
France should have been toast but Sexton had missed a crucial penalty, when his team were 12-6 ahead, and Ireland had wasted each trip into the opposition 22 [getting turned over three times].
But when asked about the national team captain being seen at the trial, Schmidt said: "We are in no position to comment on that".
Former Ireland Under-20s captain Ryan has always been earmarked as a future Test leader, and now has the chance to cement his promise against a powerful French pack. And I don't think he was really thinking too much about history, he just stepped and seized the moment and he did it with absolute aplomb. "I had a pop", Sexton said.
"When you know it's a serious knee injury, you're going to grimace".
Despite Irish failing to score a try, a win is a win and this success will pour confidence into the Irish as they bid to claim a first Six Nations title since 2015.
