Besiktas sporting director Ceyhun Kazanci says talks have taken place with former England star Dele Alli.
The midfielder has struggled to bring his best form to Turkey after he moved on-loan from Everton.
He has managed to score for Besiktas, but has not impressed fans in the way they were expecting.
Alli even received criticism from Besiktas coach Senol Gunes recently, but was defended by their sporting director.
“Dele Alli is working intensively. We had intense talks with him before we signed him," Kazanci told Turkish broadcaster TRT Spor.
“Senol is famous for returning many players whose careers have been on the decline. We hope that he will be better in the second half of the season."
