Defender Ben Gibson has joined Burnley on a four-year deal from Middlesbrough for a joint club-record fee.
The 25-year-old moves to Turf Moor for £15m, matching the fee paid for Chris Wood last summer, and becomes the Clarets' first signing of the summer transfer window.
Gibson made 38 Premier League appearances for the Teesside outfit in 2016-17 before their relegation to the Championship at the end of the season.
"I'm absolutely delighted. It's a big step for me. I've played for Middlesbrough for 15 years since I was a boy so it's a huge step and one I'm really, really excited about," Gibson told the official Burnley website.
"I've been to the training ground and met a few of the boys and the place seems like it's certainly a club that's on the up and certainly a club to be excited about playing for.
"There's a good feel about the place. Burnley is a club that recently has had some fantastic success and I've had some great battles against them myself and I'm looking forward to wearing their colours."
The former England Under-21 international received a call-up to the senior squad in March 2017 for a World Cup qualifier, but did not win a cap.
