Glasgow Warriors head coach Gregor Townsend hailed his side's heroic defensive effort after their famous 23-14 win at Racing 92.
The Scottish side claimed only their third win on French soil to give their hopes of qualifying from the pool stage of the European Champions Cup a huge boost.
Tries from Alex Dunbar and Ali Price put Glasgow on the road to victory a year on from a defeat in Paris that all-but ended their European hopes.
Argentina wing Juan Imhoff put Racing ahead in the opening exchanges before Carter scored late-on, but it was not enough to lift them off the foot of pool one ahead of next week's return clash at Scotstoun.
And Townsend hailed his Warriors after a herculean defensive effort.
He said: "It was great seeing the players going out there and performing.
"We missed that opportunity last year with a couple of errors that they capitalised on but today we looked after the ball really well and took our chances especially in the first-half.
"We were outstanding in defence, not only in general but in our line-out defence where they are really strong.
"To get the score just after half-time was crucial, it meant they would have to play and force things and we just had to be really strong defensively.
"The effort the players put in defensively won us that game."
Finn Russell was named man-of-the-match after he got the better of opposite number Carter and kicked 13 points.
The Scotland outside-half sent Dunbar over for his try and made a half-break before Price's second-half score, but he will have to do it all over again when the French champions arrive at Scotstoun next weekend.
Townsend has urged his men to back-up their famous triumph with another faultless performance, adding: "Finn loves these big games, he loved it, he kicked very well.
"There was a number of man-of-the-match performances out there today. Alex Dunbar was excellent, the back-three were excellent dealing with kick chases and Ali Price did really well.
"It will be difficult next week, we know they will come with more knowledge of us and they will throw everything at us.
"They have only played two games so far and they are a quality side so we have to make Scotstoun difficult for them."
