Adelaide United have solidified their place in the A-League top six but coach Maro Kurz felt they missed too many chances in their 2-1 win over Western Sydney.
The Reds now have a 10-point gap over seventh-placed Newcastle Jets, although they have played a game more than last season's Grand Finalists.
They bounced back from their 2-1 defeat away to Sydney FC, which was their only loss in the last six matches.
Vince Lia and Craig Goodwin netted for United, Goodwin scoring for the third game in a row.
Kurz was happy with the victory but said the game should have been killed off earlier at ANZ Stadium.
"It was a hard game against a good opponent; we always made it too hard for us because we can score earlier the third or the fourth goal," he said.
"When we score a goal we always want to score the next one. And in the second-half as well because we had a lot of big chances – that's maybe our weakness that we have too many chances and don't score enough goals."
Wanderers equalled their club record with a fifth consecutive defeat and their coach Markus Babbel admitted the hectic A-League schedule is creating problems for his squad.
Babbel had seven players unavailable through a mix of injuries, suspensions and national duties, with five of the team aged 20 or under.
The team struggled with Sydney's high temperatures and have just a four-day turnaround for the road game with Melbourne City.
"Many players have never had five games in a row, now they are playing 10 or 12 or 13," said Babbel. "Normally we have to change, but I can't, I don't have the players."
Adelaide United are 12/1 to win the Grand Final and 50/1 to win the minor premiership.
