Rhys Williams has penned a five-year extension with Liverpool before joining Swansea City on a season-long loan.
The 20-year-old enjoyed a breakthrough season at Anfield and will now gain further senior experience in the Championship.
"I am buzzing, I have heard nothing but good things about the club and the manager from a few of the lads back at Liverpool, so I am delighted to be here," said Williams.
"I am looking forward to getting some good results on the board and keeping us moving forward.
"I spoke to a few players about it, and they all spoke so highly of the football and the place itself, it's a club with a good history behind it.
"I was keen to come here, it was one of the places I wanted to come to because of the football they play.
"I believe it will stand me in good stead for next season.
"Obviously last season was important for me. No-one could have been prepared for last season, especially me, with all the injuries suffered by centre-backs.
"The last five games of last season were described as five finals so I knew if I could do something good there, I would have put myself in good stead.
"It was a once in a lifetime experience and I hope I can take what I learned and show that here. I have played against some good players, and every game comes with a different challenge, so I hope that shows in my time here.
"I am looking for regular football and I hope I can find that here at Swansea."
