Besiktas are eyeing Crystal Palace striker Christian Benteke.
Besiktas management are keen on bringing the Belgium international to Turkey this summer.
And Fanatik says they've been encouraged after learning that Benteke has rejected a new contract offer from the Eagles.
Besiktas are in contact with Benteke's minders ahead of the summer market.
However, the centre-forward won't make a decision about his future until after the Euros.
