Tom Carroll has completed a £4.5m move from Tottenham Hotspur to Swansea City.

The transfer sees Carroll, who spent the 2014/15 season on loan with the Swans, leave the club he joined as a trainee in 2010.

Watford-born Carroll made his Spurs debut in a Europa League tie at Hearts in August 2011, and had loan spells at Leyton Orient, Derby and QPR as well spending the 2014-15 season at Swansea.

He has signed a three-and-a-half year deal at the Liberty Stadium and is pleased to have made the switch to a club he is familiar with.

Carroll told the official Swansea website: "It definitely helps knowing quite a few of the lads from my loan spell, while I know (assistant coach) Nigel Gibbs and (head of physical performance) Karl Halabi too.

"Knowing the players and staff allows you to settle quicker than normal.

"It can take time to settle in at a new club, but having some familiar faces around the place will help me get going straight away.

"I know what the club is about too, and I know the playing style suits me so that was a big factor in me coming here."

Carroll made 56 appearances in total for Spurs, although only four of his 25 starts came in the Premier League.
