Leicester City completed the transfer of Caglar Soyuncu from Freiburg on transfer deadline day but he has still yet to join the club.
Fears arose after the Foxes did not give Soyuncu a shirt number in their latest squad update.

The delay is due to Soyuncu yet to be granted his work permit.
The Turkey international’s agent Mustafa Dogru informed Turkish-Football that the work permit application was formally submitted on Monday in the German city of Dusseldorf.
Soyuncu is expected to be given permission to play in England by Friday.
The 22-year-old already has a deal in place with Leicester to complete his five-year deal, subject to his work permit.
Dogru expects the defender to join his first Leicester training session by Monday.
The initial transfer fee was £18.3m [€20.5m] and could rise to £20m [€22.5m] with bonuses.
Twenty-five percent of the transfer fee will be paid to Altinordu who had a sell-on clause deal with the Bundesliga outfit from his transfer in 2016.
Leicester first expressed an interest in Soyuncu back in January 2017, making an enquiry for the Turkey international.
Soyuncu rejected three Premier League sides before striking a deal with Leicester. A total of six English sides scouted his last international game.
The Foxes made assurances that they view the defender as being a first-team player.
The defender will become the second Turkish international after Muzzi Izzet to play for Leicester.
