Matt O'Connor was delighted as Leinster began their first Heineken Cup campaign under his tenure with a victory over the Ospreys.
Having racked up three Heineken Cup titles and one Amlin Challenge Cup title under Joe Schmidt, O'Connor has a giant pair of boots to fill in Dublin.
But he began in near-perfect fashion as the European heavyweights claimed a rare win at the Liberty Stadium and denied the Ospreys a losing bonus-point.
"It was a really gutsy performance, the try we scored in the first-half after they had early dominance turned the game and we held on," said O'Connor.
"The boys really fought for each other.
"We had a few things to address after losing to Munster and full credit to the boys the stuck their hands up after last week. We were very critical and robust in our conversations at the start of the week and we got the response."
O'Connor, who took the reins at Leinster following a three-year stint as an assistant coach at Leicester Tigers, is refusing to get carried away.
They face Castres Olympique at the RDS next weekend and face Northampton Saints in the December double headers.
And he reckons denying the Ospreys a losing bonus-point could be crucial in the outcome of Pool One.
"We're looking at it in realistic terms, it's one of six for us, you have to make sure you bring that to every game in this tournament," said O'Connor.
"The result's important, the four points are important but we have to be a lot better than that to go further in the competition.
"Potentially, denying them a bonus-point could be important because this is cup rugby and it's important you get as much out of it as you can and give the opposition as little as possible.
"It was a pretty intense contest. To be fair, I thought it was a great game of rugby."
The atmospheric Stade Vélodome in Marseille looks set for a 40,000 plus attendance for the Heineken Cup semi-final clash on Sunday, 27 April between reigning champions, Toulon - gunning for a fourth European final in five years - and Munster Rugby, who have reached a record 11th tournament semi-final.
