Adelaide United have taken a lot of encouragement from their win over defending champions Melbourne Victory, says Craig Goodwin.
The Reds extended their unbeaten run to four games and now have a seven-point cushion inside the Finals Series places.
Marco Kurz's side scored their goals in a three-minute spell in the first half, Goodwin getting them off the mark and Ken Ilso adding a second as they ended Victory's nine-match undefeated streak.
Goodwin, who now has 10 goals in all competitions this season, was happy with the first-half display in particular against Victory and hopes that form carries over into their clash with last season's minor premiers Sydney FC.
"It was a good performance, very intense with the pressing obviously we were clinical," he said. "I think that's probably the thing we've lacked the most, that clinical finishing.
"The game before against Wellington we had 32 shots and no goals, so it's probably the one thing that's restricted us from picking up more points, but hopefully we can improve on that in the coming games as well."
The 27-year-old scored his goal against Victory after excellent lead-up play from Isaias and Nikola Mileusnic.
He paid tribute to Isaias, saying: "He's our captain and he's such an important player for us. He leads with his performances on the field and last night he was first-class from start to finish."
Kurz will have Vince Lia available again after suspension when the Reds take on Sydney FC on Sunday.
Three of their five wins this season have come on the road and they now face three consecutive away games before finishing January by hosting bottom side Central Coast.
Adelaide are 14/5 to win their next game against Sydney FC, who are 19/20 with the draw 13/5.
