Kansas City Wizards head coach Peter Vermes admits his side did not sustain their performance for a full 90 minutes in their 1-0 home loss to Columbus Crew.

The Wizards were beaten by a 64th minute Emilio Renteria goal to make it a six-game winless streak which Vermes says can change quickly if his players work hard.

"We did not play well enough to win the game. We had a couple of actions here or there, but it wasn't sustained," he said.

"I'm very frustrated, and I know that the players are as well. There have been several games where we played well, but things have not fallen our way. We'll go back out and keep trying to make it happen on the training field, and then we'll try to execute in the game. This stuff can turn very quickly."

On a positive note for the Wizards, two players - Jonathan Leathers and Teal Bunbury - were rewarded with their first starts for the club.

"I thought that Johnny did a good job throughout the course of the game. It's hard for him to get a 90-minute game because he has not played a lot, but I thought he did well, and I thought Teal had some very good actions for his starting debut. I thought both of them did well," Vermes added.

Bunbury said it was great to grab his first full MLS debut and said he tried to do the little things to help his team but was disappointed they cam up short.

"I felt good. I just tried to work hard and help my teammates out, working off the ball, trying to get back to places defensively, and when I got the ball just try and make things happen," the 20-year old said. "Unfortunately we couldn't get a win, so I'm definitely disappointed about that. Overall, I think we did well as a team. We created chances, but we've just got to find a way to win."
