The A-League club were punished by the Japanese outfit at home last Wednesday but are intent on producing a much better performance when they travel to Japan next week.
"We didn't turn up and paid the price, that won't happen again," Kwasnik told the Express Advocate.
"The key for us is to get our heads up and stick together and work harder before the next match in Japan. We will be better."
The Mariners will need a win or at least a point from the match and hope that Tianjin Teda can defeat Pohang Steelers to keep their hopes of progressing to the round of 16 alive.
