The club captain, who made his 444th appearance for the Blues on Wednesday night, has less than seven months remaining on his existing terms.
However, according to Eurosport, several of Azpilicueta's teammates are shocked that the club legend is yet to pen a contract through until the end of next season.
The report adds that the 32-year-old has also been left frustrated at a time when he is attracting interest from the likes of Barcelona and Atletico Madrid.
As it stands, Azpilicueta, who has not played in his homeland since 2010, can speak with both clubs next month regarding a pre-contract agreement. body check tags ::
