Skysports.com understands Osasuna have made an enquiry for Celtic's Evander Sno.
Sno has so far struggled to establish himself in Celtic's side this season and has made one fleeting appearance as a substitute in the UEFA Champions League qualifier with Spartak Moscow.
The summer signings of Scott Brown and Massimo Donati have increased competition for places at Parkhead with Gordon Strachan having a plethora of options available to him in midfield.
Osasuna are keen to bolster their squad before the close of the transfer window and are looking for midfield reinforcements.
The Spanish side have been linked with a move for Rangers' Brahim Hemdani, but after seeing their overtures for the Frenchman snubbed they are thought to have turned their attentions to Sno.
Osasuna are believed to have asked about taking the former Feyenoord man on a season-long loan.
However, Celtic are thought to have rebuffed Osasuna's enquiry as they do not want to let Sno leave.
