The Brazilian playmaker has been linked to the European giants throughout the season, despite signing a new long-term contract at Anfield earlier in the campaign.
Previously, Balague claimed that Barcelona have no interest in the 24-year-old, and he has reiterated that stance.
He told Sky Sports News: "This has turned into a weekly question. His entourage is clearly working to move him to the Nou Camp. There are different reasons why Barca will not go for him.
"One is the cost and the other is they think he's a forward rather than a midfielder. And of course they are completely sorted in attack.
"They are looking for a different type of midfielder. Nobody doubts Coutinho's quality but Barcelona don't have the money to be getting three or four top players for their first-choice lineup."
Coutinho has scored 12 Premier League goals and created seven assists in 30 Premier League appearances this season.
