Adelaide United has continued Sydney FC's horror start to the season with a 3-1 win at the Sydney Football Stadium tonight. Sydney FC 1 (Keller 58th) Adelaide United 3 (Van Dyk 9th, 53th, Leckie 37th)

The result leaves the reigning champions rooted to the bottom of the table, whilst ironically Adelaide, last year's bottom team, now heads the league after five rounds.

A double from Sergio van Dijk - the first a marvellous freekick - came in between Mathew Leckie's 37th-minute goal to silence the home crowd.

Stephan Keller's 58th minute goal restored some hope for Sydney but Adelaide was too strong on the night.
