Defending champion Los Angeles Galaxy sits in last place of the Western Conference and faces upcoming games without Euro 2012-bound Ireland striker Robbie Keane and Landon Donovan, who's on U.S. duty.
"It's not as much an issue as it is for the team to play better as a group. That's the challenge," L.A. coach Bruce Arena told Nick Green. "We haven't won with those players, so I don't think it's going to hurt us."
The 3-6-2 Galaxy host second-place San Jose on Wednesday.
"Of course I'm worried," Arena said. "We need to start winning games, no question about it. Over the last couple of weeks the guys who started off real fast have slowed down. We've got to position ourselves to win some games."
