Houston Dynamo coach Ben Olsen wants a sharper offensive performance when his club hosts the Colorado Rapids on Saturday.

The Dynamo (4-5-0, 12 points) have struggled to capitalize on possessions around the box, a trend that Olsen said must improve.

"We are a little toothless in our attack," Olsen said. "We have to be a little more patient and balanced and figure out the final third."

Houston lost 2-0 to Austin last Saturday, even though it held 53.9% of the possession. Prior to the loss at Austin, the Dynamo had won two straight matches by 1-0 scores but have been outscored 18-12 this season.

Guilherme Augusto leads the Dynamo with five goals and four assists.

"For 100 minutes a week, you've got to summon something, summon the best in yourself," Olsen said. "And that's the responsibility these players have and I have."

Colorado (4-5-1, 13 points) will look to bounce back after a 3-1 loss to the Vancouver Whitecaps last Saturday. Rafael Navarro tallied the lone goal, and the Brazilian forward leads the Rapids with seven goals and four assists. He also has 19 shots on target.

Navarro's goal last week marked his 50th regular-season goal contribution in his fourth year with the club. He's the eighth Colorado player to reach the milestone.

Rapids defender Keegan Rosenberry said the Rapids have to get off to better starts.

"From the first whistle, we have to show up as ourselves," Rosenberry said. "We have to have that bravery and meet the demands of the game better."

In the first matchup between the two teams, the Rapids rolled to a 6-2 home win over the Dynamo on April 11. Kosi Thompson and Navarro each scored a brace in that match. But since then, the Rapids have gone 0-2-1 in league play.

"We have to do the necessary dirty stuff to win games," Colorado coach Matt Wells said. "Our football warrants that."
