New Chelsea boss Mauricio Pochettino says a captain is yet to be decided.
Pochettino must make a decision after Cesar Azpilicueta's departure for Atletico Madrid.
He said, "First of all we need to build the squad and then I need to look at all the players before making a decision.
"I need to feel the players, feel the commitment, the character, the personality. One thing is we are working with them for positive and not so positive.
"First of all we need to close the club and the squad and then we have many players with experience and we will decide."
