Cesar Azpilicueta has played a number of matches at right-back this season after spending most of the last campaign on the left.
The Spain international has established himself as a key player for the Blues following a move from Marseille in 2012.
Azpilicueta has already made 141 appearances in all competitions for Chelsea, helping his side to a number of trophies, including the Premier League title as well as the Europa League and Capital One Cup.
Despite arriving at Stamford Bridge as a right-back, Azpilicueta was quickly deployed on the opposite flank by Mourinho following the Special One’s return to west London in 2013.
Experienced stars such as Ashley Cole and Filipe Luis were unable to find a way past the 26-year-old, with Baba Rahman the latest challenger for his position.
However, an injury to the out-of-form Branislav Ivanovic has seen Azpilicueta play a number of games in his natural position, but the former Osasuna youngster is adamant that he is ready to play on either side of the backline as Chelsea look to claw their way back up the table following a poor start to their title defence.
He told the club’s official website: “I think at this stage last season I hadn’t played so many games on the right but my goal and my target is always the same – to help the team.
“I feel comfortable in both positions so I’m ready for the manager when he wants me to play.”
