Crystal Palace have made an approach for Besiktas forward Cenk Tosun, according to a report.

The 26-year-old has scored 11 times in 20 appearances for the Turkish giants this season, including four goals in the Champions League.

Tosun's form has led to a number of top European clubs reportedly staking their interest in the player, but Turkish outlet Haber believes that the Eagles have lodged a £17m bid.

The report, however, also quotes Besiktas president Fikret Orman as saying: "We are not sure Cenk will go. We want Cenk to stay. €20m (£17m) is a very small for Cenk."

Tosun, capped 24 times for Turkey, is under contract to Besiktas until 2019.
