Sheffield United are to sign Fulham defender Jon Harley for an undisclosed fee, reports BBC Radio Sheffield.
Harley has had two previous loan spells with the Blades
The 24-year-old, who has had two loan spells at Bramall Lane in the last three seasons, has agreed a three-year contract with the Blades.
Maidstone-born Harley began his career at Chelsea but made just 30 league appearances while at Stamford Bridge.
He spent three months on loan at West Ham this season, but was deemed surplus to requirements by boss Alan Pardew.
Blades boss Neil Warnock has tipped Harley to do well next season.
He said: "I expect him to complement our left side which is a strong part of the team. I'm hoping he can play a big part in helping us get where we want to.
"Our fans like him but I still think he has it all to do and he mustn't rest on his laurels. But I can't see anything but good times ahead for him.
"He's also a smashing lad in the dressing room and that's another reason why he will be an important signing."
