Leganes signing Andriy Lunin must wait to make his LaLiga debut.
The Ukraine international has arrived on a season-long loan from Real Madrid, but will be prevented from facing his parent club this weekend.
Real insisted on a 'fear' clause being included in their agreement.
Lunin said: "This [about the fear clause] is a matter of policy. I do not know if I can value these things. My duty and my obligations are to be a good player and do everything to help the team. Nothing else.
"Leganés is a club that everyone respects. Not only in the dressing room of Real Madrid, but by all teams. About possible players that may come, it is an individual decision. I'm not the one to say anything."
