Chelsea assistant manager Steve Holland has praised Cesar Azpilicueta for his "absolutely immense" attitude this season.
The right-back opened the scoring for the Stamford Bridge side during their 2-0 win over Arsenal this evening, which secured them a place in the League Cup quarter-finals.
Holland told BBC Sport: "Cesar is a very popular guy and I know Jose Mourinho singled him out for being the type of player that, although he has had very little opportunity, his attitude has been absolutely immense and a lesson to all.
"I'm not sure he should have been there for goal but the fact that he had drive to get there is a testament to him."
The draw for the last eight of the League Cup takes place tomorrow.
