Western Force coach Michael Foley says that while his team showed some of their best form of the season against the Sharks they need to learn to hold their momentum.
The home side powered out to a 10-7 half-time lead before being run down in the second half with the Sharks scoring their second of two tries to help seal the 10-point margin.
Foley said while the first half included some of his side's best rugby of the season, his side's inability to continue that momentum through the second term was costly.
"We'll learn from that," he said.
"For all of us there's an overwhelming sense of disappointment because of how well we played in the first half and how well we controlled the game.
"To let that slip, you feel very disappointed."
"With experience definitely comes those lessons but it's one of those games that you sit there and think about and wish you could play again."
The Western Force return to nib Stadium next Saturday to face the Highlanders.
