Carlos Carvalhal's men secured their first win in six Championship games when they beat Nottingham Forest 3-0.
The Italian's recent fortunes appear to have been a key reason why the Owls had gone five games without a victory before their clash with Nottingham Forest last weekend, as he had been sent off in two of the games and suspended for the other three.
And after Carlos Carvalhal's men thrashed Forest 3-0 at the City Ground, Hooper suggested that it was the former Watford man's return that was instrumental in changing their fortunes.
"I think we did miss him and it showed in what was a nice win," he told the Star.
"He's the top scorer so you are going to miss him when he is not there.
"It's clear in a way, although we still kept clean sheets and had a fair few draws when he was suspended.
"We just didn't take our chances in that time but we did on Saturday."
While the 26-year-old did not get on the scoresheet on Saturday, he did provide an assist for Hooper's goal which doubled Wednesday's lead on the hour-mark after Aiden McGeady had put them in front.
As well as Wednesday's form as a side, it appears that Forestieri's return also greatly benefited Hooper's own luck in front of goal, as the assist proved.
During their winless run, Carvalhal's men had managed just one goal, and despite starting every game during that time, it was not Hooper that scored it.
So perhaps, not only will Forestieri's return see Wednesday's results improve, but it will also see Hooper return to his ruthless best, which could prove ominous for those sides battling for a play-off spot.
