According to Cadena SER, the Brazilian is unhappy at Camp Nou and his representatives have already told Barcelona about his decision to leave the club this summer.
The Spanish newspaper is also reporting that the former Liverpool star is distressed by his failed move to the La Liga champions and his failure to make an impact at Barcelona.
It had reported that Coutinho is among the seven players placed on Barcelona’s transfer list.
The Catalan club are open to selling Coutinho this summer, but are demanding a transfer fee of at least £80million for the player.
Coutinho has failed to impress since arriving from Liverpool in a £105million deal in January 2018 despite playing his part in two La Liga title wins.
A disappointing performance against his former club at Anfield saw Barcelona crash out of Europe, raising more questions about the 26 year old.
Coutinho has drawn interests from Liverpool, Manchester United and Paris Saint-Germain in the past few weeks.
