Above is a tweet saying Chelsea of the English Premier League will play in Seattle this summer.

However, the Sounders say nothing has been confirmed. And this would be a rematch, as Chelsea visited Seattle in 2009, with the English side winning 2-0. And with a world of soccer clubs out there, I'm not sure another Chelsea visit will stir the faithful much.
Will report more as I can.
