Besiktas chief Ceyhun Kazanci says Dele Alli will fulfil his season-long loan.

There's been talk of Besiktas sending the England midfielder back to Everton in January due to disappointing form.

But Kazanci says: "No one can answer whether Dele Alli can come back properly, but he is working very hard.

"He is a player who was worth around 100 million euros three years ago, but he has had this dip in form. Senol (Günes, new coach at Besiktas since the end of October) is known for helping players back after their careers have gone downhill.

"We hope that he will get better during the second half of the season."
