Besiktas signing Miralem Pjanic has again taken aim at Barcelona coach Ronald Koeman.

Pjanic left Barca for Besiktas last week on a season-long loan.

“Besiktas wanted me strongly in the last days of the transfer market and I couldn't stay in Barcelona with Koeman, I would have lost another year and I didn't want to," Pjanic told Tuttosport.

“Koeman had an attitude with me that no one understood, not even [Lionel] Messi. Leo, last year, told me several times: 'But why doesn't he let you play? Has something happened?.

“Besiktas are the Turkish champions, they are in the Champions League and… they have a black and white jersey. They welcomed me in a great way, it will be another great challenge."
