The Swans confirmed the signing of 19-year-old left-back Stephen Kingsley on their official website last night as the defender signed a three-year deal with the club.
The Scottish U19 international had a medical at the club on Monday and has joined fellow Falkirk youngster Jay Fulton, who joined Swansea in January.
The defender made his debut with the Scottish side at just 16-years-old and had gone on to make over 100 appearances with the club.
Kingsley's arrival looks set to pave the way for Ben Davies to complete his estimated £8 million switch to Spurs as Mauricio Pochettino's first signing since taking over as manager at the North London club.
Several reports have suggested that Tottenham are close to agreeing a deal with The Swans for the 21-year-old left-back who would bolster a position at Spurs that needs adding to.
Danny Rose played at left-back for much of the last campaign for Spurs, with Jan Vertonghen also covering at fullback when required.
However, neither were able to impress enough and Pochettino feels that Davies' arrival will improve the side ahead of the new season.
Davies has made 70 Premier League appearances over the past two season's, scoring three times and is also the first choice left-back for Wales.
Spurs are also looking at bringing in Wilfried Bony from The Swans and could make a double move for the Ivorian striker and Davies.
