Western Sydney boss Josep Gombau says his side lost two points in Wednesday's 1-1 draw with Adelaide United, bemoaning their failure to convert a trio of first-half chances.
Wanderers had the better of the first-half chances, with Steve Lustica's close-range effort blocked on the line.
The hosts went ahead when Jack Clisby fired home at the back post on 52 minutes, but Apostolos Stamatelopoulos levelled with four minutes to go.
The result means Wanderers missed the chance to move level on points with fourth-placed United and fifth-placed Melbourne Victory, remaining in sixth spot.
"We think we deserved to win the game," Gombau told Fox Sports.
"In the first half we had good chances. We had three good chances to score and one in the last second of the first half.
"This changed the game if we went into half-time 1-0 up.
"We scored early in the second half and I think the game was open.
"The corners we concede came from an action where we had a transition to score a goal.
"I'm disappointed because at the end we lost two points. It's football, we need to recover fast."
Gombau also defended his decision to make three substitutions in the second half, which appeared to halt Wanderers' momentum as they invited late pressure.
"No. At the end, every sub was for something," Gombau said.
"We had Chris Herd with a yellow card and he's also a player for a long time hasn't played games. We needed to change him.
"After that, my feeling was we needed more to keep the result a strong player in the middle like Hamill.
"(Lachlan) Scott played well in brisbane and he deseerved to play here also."
Wanderers are next in action away to Wellington Phoenix on Saturday.
