Nuhiu was brought on when the Owls were 3-1 up against Wolves, and he helped his side round off the triumph in style.
The Austrian striker managed to tee up Gary Hooper in the final minute of the contest, and Carvalhal was delighted with the quality of his assist.
“Atdhe came on in the final eight minutes and had a good chance to score but he gave the ball to Gary Hooper,” the Portuguese boss said.
“That is what I like and appreciate. These little things show that they are concentrating more on the team than the individual performance.”
Nuhiu’s performances have been criticsed by Wednesday supporters this season, and he is a player who divides opinion at Hillsborough.
The 26-year-old has a presence up-front which can trouble opposition defences, but he has only scored three times in 23 appearances.
His lack of mobility can also be an issue, but his willingness to help others get on the scoresheet is an endearing trait.
Wednesday’s 4-1 win over Wolves has lifted them into seventh place in the Championship table, and they are now just one point away from the play off places.
