Preview: The soccer-mad city of Seattle gets a marquee match-up on Wednesday as their Sounders side go up against the champions of Europe, Chelsea.

The match is Chelsea's first of a pre-season that could be vitally important with the Blues. Despite their glory-filled end to the last campaign, Roman Abramovich has sanctioned a radical overhaul of the squad at Stamford Bridge this summer and newly-instilled permanent coach Roberto Di Matteo will be eager to implement his own philosophy.

Having taken over from Andre Villas-Boas, Di Matteo somewhat rode his luck as Chelsea hung on for victories against both Barcelona and Bayern Munich to claim the Champions League for the first time in their history. Given the players that Chelsea have signed and have been linked with this summer, it is clear that Di Matteo wants his side to produce a more proactive and attractive brand of football in the coming season.

Much of the focus will be on the two confirmed signings thus far this off-season, Eden Hazard and Marko Marin. Both will be looking to make their first appearance for Chelsea against the Sounders.

The Blues have taken a strong squad to the United States, missing only the five players who progressed beyond the group stage at Euro 2012--John Terry, Ashley Cole, Florent Malouda, Raul Meireles and Fernando Torres.

While Chelsea are in their pre-season, Seattle are currently enjoying a mid-season break from the Major League Soccer season. The Sounders stretched their unbeaten run to four games on Sunday with a 2-2 draw with the New York Red Bulls. They currently sit in third spot in the Western Conference.

For Seattle, the match also adds as a farewell to Roger Levesque, who will be retiring following the clash with Chelsea. The 31-year-old is a fan favorite after spending nine years in Seattle and having progressed with the club from the old United Soccer League to MLS in 2009.
