Barcelona are desperate to finally land Coutinho after seeing their offers rebuffed last summer.
Liverpool have been reluctant to part with their star man but Balague claims they are now considering cashing in on the 25-year-old.
“About Coutinho. Barcelona will soon make an offer of €110+40," Balague tweeted.
“Chairman Bartomeu feels in debt to him for how hard he's trying to go to FCB. Their top players want him.
“LFC have changed their tone but have not put price to him. They will act when offer arrives. Which it will."
