DeAndre Yedlin trained with Tottenham Hotspur for the first time on Wednesday after completing his move from the Seattle Sounders.
Spurs agreed a summer deal to sign the USA international full-back for next season, and then brought forward his switch to White Hart Lane to January.
Yedlin has been given the number 12 shirt by Tottenham and is now available to play in their Premier League match against Crystal Palace on Saturday, although he is likely to have to wait for his debut.
The 21-year-old's arrival increases the likelihood that Kyle Naughton will leave Spurs during this transfer window, with Swansea City said to be weighing up whether to meet his £5m valuation.
