Crystal Palace brought in Everton striker Cenk Tosun on loan till the end of the season in January, and the Turkey international has featured in three Premier League games, scoring once.
The 28-year-old played just five league games for the Toffees during the first-half of the campaign and will be eager to leave Goodison Park on a permanent basis for regular playing minutes.
That appears to be on offer at Selhurst Park, and Palace chairman Steve Parish has revealed that there is an option to buy him when his loan spell ends.
