Here's a highlight quote:
“I’m definitely excited to get some playing time with the (Impact),” he said. “It was difficult to get playing time over in Seattle with all the midfielders they have. So coming into this situation where everybody is kind of new, it’s a little bit easier to maybe get a spot whereas the coaches at Seattle had their minds already set on who they wanted. Here they’re not as set. I’m sure they have an idea, but I’m definitely going to try to get some minutes.”
Meanwhile, here's a general overview on the Impact from MajorLeagueSoccerTalk.com.
The Sounders and Impact play once this season: June 16 in Montreal.
