The former England Under-21 full-back completed his move from north London to south Wales last night for a fee understood to be £5m.
Naughton has penned a three-and-a-half year contract at the Liberty Stadium and could make his debut in Swansea’s FA Cup fourth-round tie at Blackburn tomorrow.
“I’m pleased it’s all done because there has been talk since the summer over a potential move,” said Naughton.
“My main aim is to start playing regular football again.
“I know it’s going to be a tough challenge because there are some very good players here, but that’s my goal.
“I’ve had quite a few loan moves over my career, but I actually played 34 games last season for Spurs, which is a fair amount. The main problem for me, however, was that I was still in and out of the team. That’s difficult at times.
“I’m sad to be leaving Spurs because it’s a great club. I was there quite a while and the lads are a great bunch. But now I just want to settle into life at Swansea and try to play regularly. It all comes down to playing football – after all, that’s my job.’’
The 26-year-old joined Tottenham in 2009 after playing 40 games for his hometown club Sheffield United but went out on loan at Middlesbrough, Leicester and Norwich.
Naughton, who can play either right-back or left-back, made 74 appearances for Spurs.
