Graham Arnold has been instrumental in the careers of many of the Caltex Socceroos he'll manage when he takes over as head coach of Australia after the World Cup in Russia.
MAT RYAN (Brighton & Hove Albion)
It was Graham Arnold who saw the potential in the teenage keeper, signing him for Central Coast Mariners in 2010.
Not only that, he gave Australia's current number one a chance to play regularly with Ryan thrust into first-team action in the Hyundai A-League from the beginning of his career.
Arnold believed in Ryan and stuck with him. Ryan enjoyed three great seasons in Gosford under Arnie and now, after stints in Belgium and Spain, the keeper is playing - and starring - in the English Premier League with the high-flying Seagulls.
TOM ROGIC (Celtic)
Arnold gave the then rising star Rogic a chance to experience first-team football in 2013. After winning the Nike Chance talent identification tournament and training at the Nike Academy in England, Rogic was given a chance in the Hyundai A-League under Arnold.
Rogic signed for the Scottish powerhouse later in 2013. The 25-year-old is now a huge star at the club.
JOSH BRILLANTE (Sydney FC)
Under Arnold, the combative central midfielder has blossomed since signing for Sydney FC in 2016.
Arnold signed Brillante from Italy, where he had signed with Fiorentina (he also played for Empoli and Como) off the back of an impressive season at Newcastle Jets.
The move back to Australia under Arnold's guidance has clearly been vindicated as Brillante now gets a chance to press his claims after being very close to a Socceroos World Cup call-up in 2014.
TIM CAHILL (Millwall)
Arnold has worked with since the legend's first days in the Caltex Socceroos back in 2004.
Arnold was an assistant coach in the national team from 1999-2010 and therefore has spent plenty of time on the training track with the Socceroos great.
ALEX GERSBACH (Racing Club de Lens)
Arnold spotted Gersbach while the teenager was playing for the AIS, signing the attacking defender in 2014 and debuting for the Sky Blues at 17.
Gersbach's rise has been swift since, leaving the Sky Blues in 2016 for Rosenborg in Norway before his call-up to the Caltex Socceroos later that year.
He now plays in France with Lens.
TRENT SAINSBURY (Grasshoppers Zurich)
Another youngster that Arnold scouted (from the AIS) during his successful stint with the Mariners. Sainsbury played regularly in the heart of the Central Coast defence playing regularly under Arnold.
Sainsbury won the championship with Arnold's side in 2013 before making his name in Holland and China (including a loan spell with Inter Milan and his current loan at Grasshoppers).
These days in the national team, Sainsbury is one of the first on the team sheet.
DANIEL VUKOVIC (KRC Genk)
Arnold made an astute signing before last season to bring the shot-stopper to Sydney FC from Melbourne Victory.
Vukovic was a major reason why Sydney FC won the Hyundai A-League Championship 2016/17 Season.
It propelled Vukovic to Europe where he's catching the eye at Genk in Belgium.
MATT JURMAN (Suwon Samsung Bluewings)
Another Sydney FC player who blossomed under Arnold.
The tall defender's form caught the attention of K-League outfit Suwon Samsung Bluewings who signed him at the start of 2017.
It didn't affect Arnold's side despite losing Jurman mid-season, as they went on to win the Championship.
And the move has been successful for the popular Wollongong-born player who made his Caltex Socceroos debut last year.
MARK MILLIGAN (Al Ahli SC,) NIKITA RUKAVYTSYA (Maccabi Haifa FC)
Arnold worked with Milligan and Rukavytsya with the U23 national team (below) in 2008 and during the pair's time in the national team up to 2010.
