Besiktas have stepped up their summer business by launching a major offer for Rangers midfielder Mohammed Diomande.
The Turkish giants have reportedly submitted a bid worth between €10-12 million (£8.6-10.2 million), and talks between the two clubs are already underway.
Diomande, 23, only joined Rangers in January 2024 from Nordsjaelland, initially on loan, before the Scottish side triggered a £4 million obligation to buy later that summer. He is currently under contract at Ibrox until 2028.
The Ivorian midfielder made 54 appearances across all competitions for Rangers last season, scoring six goals. His performances had earlier caught the attention of English Premier League side Everton, but no formal offer was made.
Now, Besiktas have taken the first real step toward securing his signature, according to German outlet FussballEuropa. While no agreement has yet been finalized, the ongoing discussions point to a serious move by the Istanbul-based club.
If completed, the deal could mark one of the key exits from Rangers this summer.
