Seattle Sounders goalkeeper Kasey Keller is determined to do 'whatever it takes' to overcome LA Galaxy in the Western Conference quarter-finals.

The Sounders lost 1-0 at home to the Supporter's Shield winners on Sunday and will need to produce a winning result at The Home Depot Center this weekend to move through to the next phase.

Keller says the players are prepared to give their all as they strive to keep their season rolling along.

"Whatever it takes, we will make it happen," Keller said. "We will do our best to make it happen."
