Episode 15 of the Quakes Cast features a look back at the 4-2 win against DC United and looks ahead to the away match at Sporting Kansas City this Friday evening. Lots of Gold Cup talk too, as Robert, Kelly, and Joe discuss the impacts of Chris Wondolowski and Ryan Johnson to their teams’ success. In fact, with the USA and Jamaica meeting in the quarterfinals, friends will be enemies for 90 minutes. Some good listener questions this week — don’t forget you can always reach us on Twitter — plus a sneak peak into what’s new at training. When the talk turns to Friday’s Soccer Night in America, the gang invites the Kansas City Star’s curator of their Full 90 soccer blog Charles Gooch onto the show to get us up to speed on everything Sporting KC.
