Juventus have rejected Arsenal's offer to take Daniele Rugani on loan, Goal reports.
The Gunners are looking to revamp their backline before next Thursday's transfer deadline in England, with a central defender and a left-back the key targets.
Celtic's Kieran Tierney remains the priority when it comes to the left-back, with the North London club already having seen two bids rejected for the 22-year-old.
But they are also in the market for a central defender.
An approach was made for Rugani, who has struggled to cement a regular starting spot at Juventus, since returning from a loan spell with Empoli in 2015.
Arsenal wanted to take Rugani on a two-year loan, with an option to buy at the end of his spell in north London.
But Juventus turned down the approach, with the Serie A champions reluctant to let the 25-year-old leave.
Although they go into the season with five central defenders, the Italian outfit is concered about the fitness of Giorgio Chiellini.
Rugani meanwhile, is happy to remain in Turin, with the defender keen to work under new boss Maurizio Sarri, who he enjoyed a good relationship with when he was his coach at Empoli.
