The sources report the 21-year-old is undergoing a medical with Spurs and that Tottenham and MLS outfit Seattle Sounders are finalizing terms.
Yedlin would remain with Seattle Sounders until the end of the MLS season and join Mauricio Pochettino’s side in January, Goal's Ives Galarcep reports.
The right back featured in three games for the United States at the World Cup, although all his appearances were from the bench.
He would become Pochettino’s fourth signing this summer following the arrivals of Ben Davies, Michel Vorm and Eric Dier.
