The U.S. coach is unhappy that it took months for one of his top national team players to land with a new team following Rangers' demotion.
After searching for a new home following his club team Rangers FC's relegation out of the Scottish Premier League's top division, Klinsmann wasn't happy about Edu having to wait until the final hours of the summer transfer window before finally landing at Stoke City.
"It was a long stretch for him the last couple of weeks and months of figuring out where he would go. For me, it was not understandable of how could a player like him be without a team basically for such a long period of time," Klinmann said. "The Glasgow Rangers situation didn't happen yesterday. it happened three months ago.
"I think the agent should have done a little bit of a quicker job to find a good club for him, not just a few days before the deadline."
The agent, Lyle Yorks, also represents U.S. international Clint Dempsey, who ended up at Tottenham after a transfer agreement couldn't be reached between his former club team Fulham and Liverpool on a deal.
Edu, a versatile American defender, had completed a medical early last week when he agreed terms on a three-year deal with the Potters, but he had to wait for details of a work permit to be finalized before the official announcement was made on Friday. He joins countryman Geoff Cameron at the club.
"It's been a hectic and a little bit of a stressful time for the players at the transfer period, but we are all thrilled that they all found clubs of a certain caliber," Klinsmann said.
Financial turmoil at the club led to Rangers being sent in to administration to be voted out of the Scottish Premier League, leaving several players, including three Americans, frantically looking for new homes.
Carlos Bocanegra completed a move away from Rangers to Racing Santandar of Spain's second division, while Alejando Bedoya left Scotland for Helsingborg since the club filed for bankruptcy and moved to Scotland's fourth tier.
Edu began his professional career in Major League Soccer in 2007 after playing three seasons at the University of Maryland.
