Azpilicueta has been heard on the pitchside mic during games leading his teammates.
"It is true that I like to prepare for the game in a certain way, with my own preparations, but now is different," he said. "When you are the captain you have extra responsibilities. You have also the Premier League and the referee's meetings.
"Sometimes you have to be involved also in the dressing room, trying to lift up the players and everybody to make sure that we are ready to start the game well and to win it. So of course you have extra responsibilities and I try to do them the best I can."
He also explained, "From the start there was a lot of uncertainty because we didn't know what was happening. Some players wanted to go back to their countries to see their families. So everyone had their own problems and I was trying to solve them and trying to help wherever I could.
"At that point we were training through the zoom calls together as well to keep fit. So from my point of view it was trying to keep everybody as close as possible, to have the feeling that we were still in the season, that we had to compete, because we didn't know if we were coming back or when. But that's the case now that we are back playing and we have the most important games of the season."
