Besiktas have completed the €7,3m signing of Inter Milan winger Ricardo Quaresma, the Turkish club have announced on their website.
The Portugal international will move to Besiktas after two years with the Serie A champions in which he found playing time very limited.
Quaresma, who cost Inter €18,6 million in 2008, has penned a three-year contract with Besiktas.
He had also garnered interest from clubs in Spain, Germany and Portugal, but has ultimately decided for a move to the Black Eagles, who finished fourth in the Turkish league.
Besiktas, who have installed Bernd Schuster as their new coach, are desperate to turn their fortunes around and have been credited with an interest in Manchester City's outcast Robinho.
Quaresma will now embark on his fourth challenge abroad, after failed stints at Barcelona, Inter and Chelsea.
