The 39-cap USA international spent last season on loan at Sunderland, making 23 Premier League appearances as the Black Cats staved off relegation to the Championship.
According to ESPN, Sunderland are working to sign the right-back in a permanent transfer with talks between the Premier League duo ongoing.
But rivalled interest from two English clubs has thrown the potential deal between Spurs and Sunderland into doubt.
According to The Daily Mail, both Hull City and Derby County have tabled £3.5million bids to sign the 23-year-old, who plied his trade with Seattle Sounders before moving to White Hart Lane in January 2015.
Hull got their Premier League campaign off to a flyer on Saturday, beating reigning champions Leicester City in a 2-1 win on the opening day of the season.
