Osasuna defender Cesar Azpilicueta is attracting big interest this season.
The 19 year-old has been a revelation this term and is top of the shopping list of Deportivo La Coruna coach Miguel Angel Lotina.
However, Cesar's progress in the last six months has also caught the attention of Athletic Bilbao, Valencia and Atletico Madrid.
The youngster is tied to Osasuna until 2012 and his contract carries a £14 million buyout clause.
