Posh will have two captains this season with midfield powerhouse Michael Bostwick the leader on the pitch and defender Gabriel Zakuani the club captain.
Manager Dave Robertson has also made goalkeeper Ben Alnwick the vice-captain on the field.
Announcing the decisions at the end of Posh’s training camp to Ireland, Robertson said: “‘Bozzy’ is a fantastic person, he is great with the young lads and is a strong senior pro.
“When selecting a captain, there are a number of things you consider, but the main thing for me is that on the pitch he is a fantastic player, a great leader and, for me, that was a simple decision.
“The vice-captain, in any absence of Michael, will be Ben Alnwick. Ben is another strong natural leader within the group.
“He has a strong personality and he is an excellent goalkeeper. His performances have been very good for us.
“I am also going to have a club captain, somebody who epitomises the football club, someone who understands the football club inside out and will support the rest of our players in understanding that and that will be Gabriel Zakuani.
“He has been here a number of years now, he fully understands the club inside out and is a natural choice in that role.
“For me, I have three very good people in those roles, they love this football club and have the leadership qualities that I want in the dressing room and on the pitch.”
Bostwick played 41 times for Posh last season, scoring seven goals, including three in the final two matches of the season.
Posh beat Cliftonville 6-0 on Wednesday and Robertson believes he currently has a “promotion-winning starting XI.”
He added that he only wants one or two more players to add to the squad.
