MK Dons have signed David Martin on a three-year deal from Liverpool.
The goalkeeper, who spent time on loan at Tranmere, Leeds and Derby this season, will return to the club where he began his career when his contract at Anfield expires on July 1.
After making his first signing since becoming the Dons' manager on a 12-month rolling contract, Karl Robinson told the club's official website: "Since I met David during my time with Liverpool, he's been a player I've admired. He left this club as a boy but he's come back a man and I think he has all the qualities to be a future England goalkeeper."
He added: "We want players at this football club that match our ambition, are passionate about playing for MK Dons and hungry for success. David certainly fits into all of those categories."
Martin said: "It's a dream come true to be back here and I'm grateful to the manager and the chairman for giving me the opportunity. The club's made incredible progress in the four-and-a-half years I've been away and, after meeting Karl Robinson, I was really impressed with how he wants to take it forward.
"I've had the chance to work with some fantastic players at Liverpool and I'm looking forward to coming back and showing the fans here how much I've improved as a player."
