The Spanish full-back finds himself behind Branislav Ivanovic in the Stamford Bridge pecking order.
That has restricted his involvement in the Premier League, with no top-flight starts made as yet this season.
Azpilicueta is, however, favoured in knockout football and played a leading role on Tuesday as Chelsea sent Arsenal crashing out of the Capital One Cup.
He claims to be 'happy' with the role he is being asked to fill at Stamford Bridge and appreciates that rotation is part of the modern game - with Jose Mourinho's Blues competing on multiple fronts.
Azpilicueta said in The Sun: "I know the manager plays with Branislav Ivanovic this season and I am not getting a lot of games, but I am still happy at Chelsea and feel I have the confidence of the boss.
"The season is still young and we will need everybody to win all the trophies we are targeting.
"I didn't play much when I arrived at Chelsea from Marseille last year either, but by the end of the season I played practically every game.
"I've had the chance to play two League Cup games this season and I also started against Schalke in the Champions League so I am happy with the work that I'm doing.
"The manager knows that when he needs me I will always try to do my best for the team in any position he asks me to play."
