Despite being all but eliminated from the CONCACAF Champions League Herediano puts out what appears to be a 3-5-2; unless the visitors are using this as an opportunity to experiment (which is entirely possible) one would expect them to attach pretty aggressively in an attempt to salvage their hopes of advancing to the knockout stage.
The Sounders start a comparatively weakened side, but given the Sounders home field advantage and relatively unconvincing display put on by the visitors playing their strongest lineup at home should give Seattle an expectation of ending the night with another three points. With a pair of holding midfielders in the Seattle (one of whom, Amadou Sanyang, is getting his first start for Seattle) the Sounders are likely looking to preserve the clean sheet as a first priority with the belief that a goal can be found somewhere before the 90 minutes are up.
