Nick Fitzgerald's excellent strike ended leaders Adelaide United's 14-game A-League unbeaten run as Melbourne City took a 1-0 win away from Coopers Stadium on Friday.
City moved up to second and within one point of Adelaide as Fitzgerald's maiden goal for the club in the 71st minute inflicted their opponents' first defeat since the 2-1 loss at Melbourne Victory on November 28.
Bruno Fornaroli – who scored a hat-trick against Sydney last weekend – almost put John van't Schip's team ahead inside seven minutes, but his header was deflected wide by the undetected arm of Iacopo La Rocca.
Bruce Djite was unable to salvage a point for Adelaide when his stoppage-time header missed the target, meaning just one point now separates the top four teams in the A-League, though Western Sydney Warriors and Brisbane Roar are still to play this weekend.
