Swansea have signed Tom Carroll on a busy day of transfer activity for the Premier League strugglers.
Tottenham midfielder Carroll joined on a three-and-a-half year deal at the Liberty Stadium just hours after Sweden defender Martin Olsson completed his move from Norwich.
The England Under-21 international, who made 18 appearances during a Swansea loan spell two seasons ago, had made only one brief appearance in the Premier League at Spurs this season.
