That’s what a source close to the situation has informed me. I don’t know any further details other than the English club will play Sounders FC in a friendly that day at Qwest Field. Details to follow at some point.
UPDATE 2:48 p.m.: Officially, this is not a done deal as far as the club is concerned. But Sounders FC is working to finalize an agreement. Unofficially, the Chelsea match stands a better chance of happening than an appearance from FC Barcelona, which has also been rumored.
