Western Sydney captain Mark Bridge insists his side shouldn't get carried away with Saturday's 4-1 win over Wellington Phoenix claiming their opponents got "tired".
Wanderers ran away with the game after being all square at 1-1 at half-time, thanks to a second-half brace from Brendan Hamill and Chris Ikonomidis' injury-time goal.
Bridge said the scoreline flattered Wanderers.
"I don't think we were at our best," he told Fox Sports.
"I think first half we were very average. Second half, they got tired.
"We did play some good football, but they got tired.
"We need to be better. If you come up against a big club like Sydney FC, Victory or City, you don't get away with the mistakes we're making."
The win lifts Wanderers above Adelaide United into fifth, although the Reds have a game in hand with five games to play.
In the race for the top six, Wanderers are now five points clear of seventh-placed Brisbane who also have a game in hand.
"Every game is important now," Bridge said.
"We're not in a position where we can rest on our laurels and not perform.
"We need to perform every game otherwise we're not going to be in the six, simple as that."
