Who should it be?
The obvious choice for the remainder of the season would be current vice captain McJosh who would also seem to be Moore's obvious replacement at centre-half. Having said that, Postacoglou has talked of building a long term project over three to four years. As McJosh is unlikely to still be playing in three years it might be time to install the captain that Postacoglou feels will see the team through this project.
The Roar Deal's choice would be Matt McKay. A foundation player and a constant in the first team, McKay bleeds orange on the pitch and never gives up. During his injured period this season it was clear that the team missed his drive from midfield and his incisive running and passing.
McKay's fitness means that he rarely needs to be substituted, rested or miss matches through niggling injuries. That kind of fitness can only be the result of hard work and a professional approach off the pitch. McKay is a scrapper, a pro and a highly underated footballer and as such fits Postacolgou's mould perfectly. Don't be suprised to see him take the armband in the next match and keep it for years to come.
