Besiktas boss Senol Gunes believes Anderson Talisca will move to Liverpool this summer.
The 24-year-old has been on loan at Besiktas from Benfica.
"Talisca was already gone at the winter break," Gunes said after Besiktas' final game of the season.
"I'm sorry that he won't be with us any longer.
"I wish he could stay for his sake and ours. He already had a deal in place."
Tellingly, Gunes added: "He might be rivals with Cenk Tosun."
Tosun left Besiktas in January for Everton.
