Liverpool midfielder Gini Wijnaldum will cost Barcelona £15m, the club have said.
Barca are in a rebuilding process having named a number of stars to leave the club, expecting huge additions as well.
New boss Ronald Koeman identified Wijnaljdum as the player he will want to work with at Nou Camp.
But Liverpool have stressed the Dutchman will only be allowed to leave Anfield if the right price is paid.
Wijnaldum was instrumental when Liverpool eliminated Barca two seasons ago in the semifinal of the Champions league, scoring twice in that encounter.
The Catalan club will be pleased to have a player like him in their ranks especially after Ivan Rakitic has moved to Sevilla and Arturo Vidal working his way out of No u camp.
