Ospreys coach Steve Tandy admits he is frustrated his side failed to gain a bonus point in their Pro12 20-10 derby victory against Newport Gwent Dragons.
The result leaves them fifth in the table, four points behind fourth placed Glasgow, with two matches remaining.
"Credit to the Dragons, the way they defended, pushed the boundaries," said Tandy.
"But ultimately I feel we should have been good enough to rattle up four tries."
The Ospreys' match against the Dragons was the second of Sunday's two Welsh derbies at the Millennium Stadium.
Despite dominating large chunks of the game, Ospreys wasted chance after chance in a scoreless first half.
A counter-attack saw Richie Rees put the Dragons ahead against the run of play in the second half.
But Tom Habberfield's close-range try and a late penalty try for a collapsed scrum gave the Ospreys victory.
The Swansea-based region travel to Italy next where they face bottom side Zebre on Thursday, 1 May.
They then host ninth-placed Connacht at the Liberty Stadium in their last league match of the regular season.
Tandy says his team will not be complacent despite facing sides below them in the table in their two remaining fixtures.
"We've just got to keep winning. We don't want to lose games now," he said.
"Everybody's talking about chasing bonus points. I do think we probably need one, if not two bonus points.
"But first and foremost we've got to get a victory, starting with Zebre."
