Wednesday confirmed Hooper's departure shortly after his final game for the Owls against QPR last week and he has already been listed as a target for his former manager, Neil Lennon, at Celtic Park.
Two of Sheffield Wednesday's potential league rivals next season, Fulham and Aston Villa, have also been credited with interest in the 31-year-old.
But if his recent social media activity is anything to go by - having also retweeted a Celtic fan's plea for his return last week - it appears Hooper only has eyes for one club.
Gary Hooper just posted this on instagram, hinting at something? A lot of people against us resigning him, but he was a brilliant goalscorer with us and for a free transfer why not? Obviously still expect the board to spend though. pic.twitter.com/dhCN4bLG61— Danny Watters (@dannyw3369) May 14, 2019
Hooper scored 82 goals in 138 games for Celtic - winning two Premiership titles and as many Scottish Cups during Lennon’s previous regime.
And while the goals continued to flow at Sheffield Wednesday, the Englishman spent much of his Owls career - including 15 of the last 17 months - sidelined through injury.
Lennon was appointed Celtic's interim manager in February and it remains to be seen whether he will still be in charge next season after Sunday's Old Firm defeat against Rangers.
