Tony Vidmar: While Aurelio is heavily linked with the vacant role at Wellington, his brother Tony has rocketed into contention with Sydney FC.

Another with little A-League experience - serving as assistant coach under Warren Joyce at Melbourne City since 2017 - Vidmar still boasts excellent pedigree as a player, which can sometimes swing things in a coach's favour.

In addition to a stellar European career, the veteran of 73 Socceroos caps coached the Australian U/17 team to one of the finest periods in their history from 2013 to 2017. Under Vidmar, the Joeys reached the semi-finals of the AFC U/16 Championship and won the AFF U/16 Youth Championship.

They also reached the Round of 16 at the 2015 FIFA U/17 World Cup, beating the likes of Argentina before a 6-0 thrashing at the hands of Nigeria soured their efforts.

WILD CARDS

Mark Crittenden: One of the lowest-profiles on this list, but certainly not for want of trying, Blacktown City coach Mark Crittenden won the 2015 NPL title with Blacktown, in addition to the 2016 NPL NSW grand final - beating Rudan’s Sydney United.

Crittenden’s Blacktown City beat Sydney United three times in a row, and four out of five times in all competitions that season, in addition to making the quarter-finals of the FFA Cup, where they pushed Sydney FC to the limit. 

Harry Kewell: There’s little doubt that the Crawley Town boss would be welcomed back to the A-League with open arms following his recent-success in England’s League Two, in addition to his previous work with Watford’s youth side.

Perhaps a little unfairly, considering what other coaches on this list have had to accomplish just to be recognised.

Unfortunately for Sydney, it’s doubtful Kewell would even take the role. With talk of promotion growing in England, Kewell has Anfield-ambitions on his mind.

Gullermo Amor: While he left the A-League, and a comfortable gig at champions Adelaide United to progress his coaching career at Barcelona, in his current role Amor is only responsible for “Institutional and Sporting Relations” – whatever that means.

If he ever gets sick of the office job and wants to sink his teeth back into coaching, the lure of a bigger club and bigger budget than he had at Adelaide United, in addition to Asian Champions League football might just prove a drawcard.

Phil Moss: He wrangled the head coaching position at Central Coast Mariners following Arnie’s departure – albeit, only for seven months.

Nevertheless, Moss has formed close relationships with key-Sydney FC players that may be uncertain over their A-League futures. Moss' greatest asset may just be stabilisation.

Should the Sydney FC board attempt to steady the ship and continue the work of Arnold - who was so dominant over his A-League opposition - Moss may just get the second chance he’s been working for.
