Racing 92 fly-half Dan Carter insists that it's early days for his new club after a 33-3 demolition of Northampton Saints.
The Top 14 side travel to Franklin's Gardens next weekend for the return fixture having moved to the top of Pool 3 in the Champions Cup.
Carter kicked three conversions and received a standing ovation from the home crowd when he was replaced in the second half.
"We know it's going to be pretty tough next week at Northampton, so it's important that we recover well. We'll enjoy this victory, but we'll be concentrating on the return match – we've won nothing and it's another huge game for us next weekend," Carter told the EPC Rugby website.
World Rugby's Player of the Year admitted to feeling a little nervous as he began his stint in France, having not played since the World Cup final, but added that he was enjoying his time in the French capital.
"I was a little bit nervous before the game but the team made it pretty easy for me by the way they stepped up. The legs were a bit heavy and my lungs were blowing a bit but after six weeks not playing it was good to get back out there," he added.
"The first kick from the touchline wasn't that easy, but I just went through my usual routine and I was pretty happy that it sailed through. That took a bit of weight off my shoulders.
"I really enjoyed the experience. The crowd were good, it's been an awesome first couple of weeks and now I just want to keep playing.
"We've a great bunch of guys and there's a really good camaraderie in the squad. We've lots of amazing individual players from different countries, there's plenty of unity and overall, it's a lot of fun for me to here."
