The Spain international committed his future to the west London club on Tuesday, capping what has been a standout year for the full-back.
Azpilicueta usurped England legend Ashley Cole as Chelsea’s first-choice left-back under Jose Mourinho last season despite being predominantly right-footed.
The Spaniard, who has eight caps for la Roja, is facing competition from summer signing Filipe Luis for a first-team spot this season.
And 25-year-old took to his Twitter to express his joy at securing another five years at Chelsea after moving to the Blues from Marseille in 2012.
