The mentioned source have assured that a Barcelona delegation headed by chief executive Oscar Grau managed to close the deal after travelling to Liverpool on Monday, and the move will be officially announced in the coming days.
The agreement was reached on Monday night, after the Brazilian informed Klopp of his decision to leave Anfield to join Barcelona.
Barcelona look set to get their wish and Coutinho will be presented at the Camp Nou this week. His arrival would uplift the somewhat pessimistic mood in Barcelona after Neymar’s departure.
The operation was closed at around 120 million euros in total. A 90 million base fee and around 30 million in bonuses, which look likely to come into effect.
Coutinho’s time at Merseyside looks to be coming to an end. The player will leave the club after four and a half seasons in which he scored 42 goals in 182 appearances.
