The French midfielder opened his Magpies account with the first goal in their 3-0 win at Hull on Saturday in Carver’s first game in permanent charge.
Second half strikes from Sammy Ameobi and Yoan Gouffran sealed a win for the visitors and left Steve Bruce’s Tigers facing a desperate battle to beat the drop.
Carver said: “Remy’s individual performance was great and we all know how important it is to get your first goal in the Premier League.
“I told him he has the ability to start producing something and I’m so pleased he has chipped in because he makes that a regular occurrence on the training ground.
“I think there is still a lot more to come from him – there will be times when he has a bad day but he has come from another league and he can still get stronger and fitter.”
The result leaves Bruce’s men firmly rooted in the bottom three and with the small matter of a trip to Manchester City on Saturday.
Bruce said: “We have to find the bit of form that the big players showed for us last year – that is the challenge ahead of us and we will go to Manchester City and try to do that.”
