Hasleby said the players were dejected after the 38-point loss to Essendon.
But the midfielder said Fremantle had learned from the match and was ready to turn its season around.
"The spirit's never really good after two losses, it was a pretty deflating loss on the weekend, we expected to probably beat Essendon," Hasleby said from Fremantle Oval on Tuesday.
"But its a challenge to the group to stay motivated and its only two weeks in, so we've still got a big amount of time to turn it around.
"We didn't expect to be 0-2. But we realise what we've been doing wrong and it's our chance now to do something about it."
Fremantle has come under the microscope for its poor skill execution and moderate clearance statistics.
Against Essendon, a Herculean effort from ruckman Aaron Sandilands wasn't enough to give his midfielders first use of the ball – the Bombers won the clearances 32-24.
And the skill errors that cost Fremantle 18 goals from turnovers against the Bulldogs resurfaced.
"I can guarantee every one of our players will be working on not only their hand skills but also their goal kicking and ball execution around the ground this week and in the coming weeks," Hasleby said.
"On the weekend at really crucial times just not nailing those goals – the team really relies on players to kick them and it's very deflating when they don't go through."
While missed shots has cost Fremantle in both games, Hasleby said the side's forward structure and a reliance on captain Matthew Pavlich wasn't working.
Fremantle had more inside 50s against the Bombers (50-49), but managed just 10 goals.
"I think at times the structure hasn't been right," Hasleby said.
"He (Pavlich) is obviously going to go as well as we kick the ball to him at times, and on the weekend we sat it on his head.
"Sometimes we're a bit too Pavlich, (Luke) McPharlin conscious and the opposition half back flankers are just falling off and getting into their space. So we have to be smarter and hit up and try and use all the forwards instead of probably just two."
Hasleby said he expected classy defender Roger Hayden to play his first game for the season this week against the Crows.
The 28-year-old was a late withdrawal from the side that lost to the Western Bulldogs in round one with a minor hamstring injury.
