The Sunderland forward left Ajax for the Premier League club in September 2025 and impressed during his debut season.
The Dutch striker scored seven goals and provided one assist in 31 appearances, 22 of them starts.
He has also caught the eye for the Netherlands at the World Cup, scoring three goals in four matches, including two against Sweden.
Several big clubs have been credited with interest in the 24-year-old in recent weeks.
Now Tuttomercatoweb report that Juventus have been offered the chance to sign him, with around €35-40m said to be enough to get a deal done.
Brobbey is seen as a possible alternative to Randal Kolo Muani, 27, who remains Juventus' first-choice target. The Frenchman currently belongs to Paris Saint-Germain.
Kolo Muani spent last season on loan at Tottenham, scoring five goals and providing four assists in 41 competitive matches.
Juventus are working through their options as they look to strengthen their forward line this summer, with Brobbey's availability offering an alternative route if the move for Kolo Muani proves difficult to complete.
Brobbey's stock has risen sharply on the back of his World Cup form, adding to the impression left by his first season in England.
