According to a statement on the club’s official website, the 23-year-old defender has signed for the Scottish club until the end of the season on a loan deal and Celtic will have an option to buy him permanently next summer.
The Hoops were in desperate need of defensive reinforcements and the signing of the talented young defender should help them massively.
The United States international needed to leave Tottenham in order to play regular first-team football and move to the Scottish Premiership could be ideal for him.
He is likely to get regular game time at Celtic and Ange Postecoglou might be able to get the best out of him.
