Arsenal have made an attempt for Fiorentina defender Nikola Milenkovic.
Il Corriere dello Sport says Arsenal's strength in depth at centre-half remains a little concerning given Rob Holding's inconsistent performances at the Emirates.
Gunners manager Mikel Arteta attempted to address that issue by putting in an offer for Milenkovic.
But the man who is valued at around £18.5million saw the offer rejected by Fiorentina.
Juventus, Inter Milan and Sevilla also approached the Serie A side about signing the 24-year-old Serbian.
