Leeds landed Antonsson from Kalmar in his native Sweden back in 2014, as then-Whites owner Cellino sanctioned a deal after the striker scored 25 goals in 46 games.
However, Antonsson struggled to make an impact in his first season, scoring just three times in 21 games, and he was deemed surplus to requirements last summer.
The 27-year-old was farmed out on loan to League One side Blackburn Rovers, and he helped Tony Mowbray's side win promotion with seven league goals in 18 outings.
Rovers haven't pursued a permanent deal though, and now the Yorkshire Evening Post report that Brescia are interested in signing Antonsson, which would mean Cellino is again sanctioning a deal for the forward.
The Serie B side – who have now appointed David Suazo as their manager – are allegedly attempting to strike a deal for Antonsson, given that his Leeds deal expires in 12 months time.
Leeds are unlikely to put up too much of a fight, but Cellino may not be the only former Leeds man to target a deal for the Swede, with Fotbolltransfers in Sweden suggesting that Malmo want to bring him back to his homeland.
Malmo are now managed by ex-Leeds boss Uwe Rosler, and whilst their paths never crossed at Elland Road, Rosler could now beat Cellino to the striker's signature this summer.
