Arsenal are weighing up making a €30m move for a young Italy defender who helped his side qualify for the Champions League last season.
Riccardo Calafiori helped Bolgona to fifth place in Serie A to achieve qualification for Europe's top club tournament for the first time in six decades.
The talented left-footed centre-back made 30 appearances to shine for Thiago Motta's side, who surprised many in Italy last term with such an impressive league placing.
However, with Juventus now chasing Motta to be their manager, uncertainty reigns at the Renato Dall'Ara Stadium - with the highly-rated Calafiori now being hunted by Arsenal as cover for their centre-back pairing of William Saliba and Gabriel.
Arsenal are ready to back boss Mikel Arteta in the transfer market this summer as they bid to go one step further and win the Premier League title next season.
While the Gunners have been strongly linked with a centre forward to boost their title challenge once more, Arteta is also in the market for a defender who can add value to the backline.
Calafiori, who turned 22 last month, is the ideal candidate, as the player - although most commonly appearing at centre-back - has also featured as a left-back and has the attributes to fit Arteta's vision for the role.
