The Seattle Sounders and Tottenham Hotspur are finalizing the transfer of U.S. national team star Clint Dempsey who is expected to be introduced as the newest Sounder as early as Saturday multiple sources told No other details –- including the transfer fee Sounders FC paid Spurs to acquire the 30-year-old forward/midfielder’s rights -- were provided. Two high-ranking Sounders employees reached Thursday evening declined to comment. One said he didn't want to jeopardize his job by confirming that a move was imminent. "But let's put it this way: I'm not surprised I'm receiving a call" that employee said. Sounders coach Sigi Schmid addressed that report later in the day telling Seattle's KJR 950 AM radio that "right now there's nothing that's nailed down and concrete." Seattle announced Thursday afternoon that it had signed veteran midfielder Shalrie Joseph to a new contract a move that opened up a designated player spot by restructuring Joseph's existing deal. That gave the Sounders the flexibility to add another high-earning star to complement current designated players Obafemi Martins and Mauro Rosales. MLS limits its clubs to a maximum of three DPs each. An email sent to Sounders GM and minority owner Adrian Hanauer wasn't returned Friday. Neither were multiple messages left for the club's communications director or to Tottenham's press department.
