Adam Le Fondre scoring goals for fun in promising sign for Sydney FC's A-League campaign

42 goals in 54 matches - that's the quality of striker Sydney FC lost after the departure of Bobo.

But new talisman Adam Le Fondre has hit the ground running - scoring three goals in his first two Sky Blue appearances.

The 31-year-old forward hit the back of the net twice, including a stunning wonder strike, in a 2-1 friendly win over Newcastle Jets on Wednesday, adding to his single goal in the 3-0 victory against India's under 23's last month.

While it's only early days, Sky Blue fans will be buoyed by Le Fondre's form in what looms as a difficult season for the club, with Steve Corica replacing Graham Arnold as manager and the Allianz Stadium development meaning the team will play at three different home grounds this campaign.

The acquisitions of Le Fondre, who scored 12 Premier League goals for Reading in 2012-13, Dutch international Siem de Jong and compatriot Jop van der Linden will go a long way to replace the departures of Bobo, Adrian Mierzejewski and Jordy Buijs - but a period of transition at the club can be expected.

The fitness of De Jong looms as an important factor in the success of the Sky Blues' campaign.

When fit, the 29-year-old attacker has showed devastating form at Dutch Eredivisie giants Ajax - scoring 10-plus goals in four consecutive seasons from 2009 until 2013.

However since 2011-12, De Jong has spent 507 days sidelined with injury that has seen him unavailable for an incredible 121 matches.

All eyes will certainly be on Le Fondre and De Jong as Corica attempts the incredibly difficult task of emulating Arnold's extraordinary achievements.
