Dan Carter believes Racing 92 have the quality to win the Champions Cup after making an impressive debut for the French giants.
The New Zealander kicked three conversions and produced a near-faultless display as Racing scored five tries to see off Northampton 33-3.
Carter said: "I was a little bit nervous before the game, I was unsure about how I would go after having six weeks off after the World Cup.
"I was blowing a bit towards the end but hopefully I can keep building on this performance because it's brilliant to be here playing for this great club.
"Credit to my team-mates they helped me so well and to have such a comprehensive win was pleasing.
"The forward pack laid the foundation all game and give us go-forward and made it pretty easy for the back-line.
"You look at the talent here, there's so many French internationals, Kiwis, South Africans, it's a real united nations. But talent is not going to be what wins this competition it's about how we all gel together but we showed out there tonight that we do come together well as a team and on our day we could beat anyone.
"Northampton will be disappointed and I'm sure they will be a different side next week."
Saints director of rugby Jim Mallinder could not hide his disappointment after seeing his side put to the sword by a rampant Racing outfit.
Mallinder was not happy with referee George Clancy after he disallowed a try for Luther Burrell just before half-time without proper consultation from the TMO because the communications equipment was not working.
Mallinder said: "We came up against a very good Racing team that started very well and put us under a lot of pressure and got the two early tries.
"I thought we were coming back into the game and then unfortunately Victor Matfield gave away the interception when we had men over and that could have made a big difference for us.
"Then we had the ridiculous situation before the break where the referee could not consult with the TMO because it was not working, the same thing happened in France last year and we didn't get anything going our way.
"I don't think it's a step backward, Racing are a quality side and you need to be at your very best to beat them but unfortunately we weren't."
