Highlanders have started searching for a new captain following the departure of Honest Moyo two weeks ago.
Moyo left the club after the two parties mutually agreed to terminate the contract as the former skipper eyed a move to South Africa.
Bosso who started the pre-season camp last week asked their fans on Twitter who should lead the team in this coming season.
With Gabriel Nyoni who was the vice-captain also gone, the armband is likely to be given to either Ariel Sibanda or Peter Mudhuwa.
Meanwhile, the season is set to commence on the 30th of March 2018.
