Jack Cork admitted it was great to be back after being reunited with the Clarets.
The former England U21 midfielder signed a four-year deal on Tuesday to leave Swansea City and become the third signing of the summer.
And Cork, who made 57 appearances for Burnley on loan from Chelsea between January 2010 and May 2011, is delighted to be back at Turf Moor.
He said: “It’s great to be back. I’ve got some great memories from the year and a half I was here and it’s good to come back and see some old faces.
“It’s good to come back and try and have another go here, especially in the Premier League.
“I’ve heard lot has changed, the whole set-up has changed and the playing staff is completely different to when I was here.
“It’s a new challenge for me and one I’m excited for and I’m looking forward to meeting new people.”
Cork, who joined the Swans in 2015 and captained the Welsh side last season, added: “They had just signed someone in the same position, we had a lot of midfielders and it was going to be a difficult year.
“The bid came in and it was something I was keen on from the go. The club was keen and I was keen, we talked about it and decided it was best.
“It’s been a busy couple of days, I had the medical yesterday and a bit extra today, flew out today and it’s good to be here.”
