Reynald Denoueix is being linked with Joaquin Caparros' job at Athletic Bilbao.
The Frenchman is a surprise candidate for the Bilbao hotseat, having been out of work since leaving Real Sociedad in 2004.
Caparros is struggling to arrest a dismal slide at Bilbao, which has seen the club drop to 18th on the Liga table.
Bilbao football chief Julen Masach was fitness coach at Real under Denoueix.
