Arsenal are in contact with Lazio midfielder Sergej Milinkovic-Savic.
Relevo says Arsenal have been in talks with Milinkovic-Savic's agents about a move to London in January.
The Gunners are open to doing business for €50m, while Lazio president Claudio Lotito is insisting on €100m to sell.
Chelsea are also known to be interested, although he is not their primary choice in that role.
The 27-year-old has been at Lazio since leaving KRC Genk in the summer of 2015 and so far this season he has five goals and seven assists in 20 competitive appearances for the Biancocelesti.
