Brentford have signed goalkeeper Caoimhin Kelleher from Liverpool to replace Netherlands stopper Mark Flekken, who has left the Bees to join Bayer Leverkusen.
The move for Republic of Ireland international Kelleher is for an initial £12.5m, which could rise to £18m with add-ons, and Flekken has been sold for a fee in the region of £8m.
Kelleher has signed a five-year contract with Brentford, who have the option to extend the deal by a further 12 months.
Liverpool have sold the 26-year-old with Valencia keeper Giorgi Mamardashvili joining them in July to compete for the number one shirt with established first choice Alisson Becker.
"I don't think it was very difficult for me to leave [Liverpool]," said Kelleher. "I felt for my own career that the time was right for me to go, to be a number one and to play every week.
"I heard of some interest a number of weeks ago. Once I knew Brentford was in for me, it was definitely one I was really excited about and wanted to do as quickly as possible."
Kelleher played in 25 Premier League games for Liverpool since making his debut five years ago
He also made more than 40 cup appearances for the Reds and won two Premier League titles, the Champions League, FA Cup, two League Cups and a Uefa Super Cup in his time at Anfield.
"We have scouted him in the past and were aware that he had a year to go on his contract with Liverpool this summer," said Brentford director of football Phil Giles.
"When Mark Flekken had the opportunity to move to Bayer Leverkusen, we immediately thought about Caoimhin as his replacement.
"As well as being a very good goalkeeper, I've rarely met a player for whom everybody has such positive words to say about his personality and character. I'm therefore confident he'll be an excellent addition to the squad."
