London - Tottenham Hotspur on Friday completed the signing of Burnley defender Kieran Trippier on a five-year contract.
The 24-year-old right-back, who is believed to have had a 3.5 million ($5.6m, 4.9m euros) release clause, moves to north London after spending four years at Turf Moor.
"When I first heard that the club was interested I didn't have to think twice," he told Tottenham's official website.
"It's such a big club and now I just can't wait to get started and show everyone what I can do."
Trippier only signed a new three-year contract with Burnley following their promotion to the Premier League a year ago but that deal included an agreement for him be allowed to move on should they be relegated, which subsequently happened.
This week, as talks progressed with Spurs, Clarets boss Sean Dyche said it was only right the club honoured that agreement.
"He made a great decision last summer to sign a contract, stay with the club, and we had to honour that in the respect that if we didn't stay in the Premier League, then we'd allow him the chance to go on," he said.
"I think that's an honourable thing to do with someone who's been such a good servant and said he'd stay with Burnley in the Premier League.
"He's a very good player and it's no surprise people came knocking."
He is the second key player to leave Burnley this summer after Danny Ings departed for Liverpool.
