Last season’s leader Mark Hughes was released in the summer and has since joined Stevenage meaning deciding on a captain is one of Bentley’s main items of business ahead of the new League 2 season.
The Shrimps boss is set to let a group of players stake their claim ahead of the opening game at Hartlepool on August 8.
Bentley said: “I’m going to work on it over pre-season to be honest.
“There’s a couple of names in the frame. There’s no reason to rush into anything.
“There’s a couple of players who are contenders but instead of making a decision now we’ve got quite a few games over pre-season so we’ll probably share it around two, three, maybe four players and we’ll make a decision leading up to the start of the season.”
The Shrimps open their pre-season campaign at Evo-Stik First Division North side Kendal Town on Tuesday, July 14.
A full first team is set to make the trip to face the Mintcakes, managed by former Shrimps midfielder Michael Stringfellow, who currently works for the club’s youth and community scheme at the Globe Arena.
