The Portuguese has clearly been impressed by what he has seen from the striker.
The Norwich forward joined the Owls in October, and while he made a shaky start to life at Hillsborough, he has started to show in recent weeks why Carvalhal signed him in the first place. And the Portuguese explained that he wished to extend Hooper's stay at the club, but conceded that it is not his decision.
"I wish to keep Gary," he told the Yorkshire Post.
"He has been my first option since the beginning. We followed him for a long time and I wish that he will stay here.
"But we will see. It is not something I can control."
The Yorkshire Post reports that Hooper's immediate future is solely down to the Canaries, so should Alex Neil wish to bring the former Celtic man back into the fold at Carrow Road, Wednesday will have no option but to continue their push for a play-off place without him.
And while some may have previously questioned whether Hooper's return to his parent club would have that much of an impact on Carvalhal's side, his recent performances have hinted that he could be a huge asset as Wednesday try to break into the Championship's top six.
His first goal for the Owls was the single bright point from a disappointing defeat to MK Dons last month. And he followed that with another strike in the hammering of Wolves, before putting in a solid performance in the victory over play-off rivals Birmingham, and then helping the club to their first away win since October in their most recent outing against Fulham.
