Lyon sporting director Juninho has confirmed that Memphis Depay has agreed to join Barcelona and is "likely" to complete a move on deadline day.
Recently-appointed Barca boss Ronald Koeman has made signing the Netherlands international a priority since succeeding Quique Setien at Camp Nou.
Depay has revived his career at Lyon following an underwhelming spell with Manchester United, scoring and assisting a combined 75 goals in four seasons at the Groupama Stadium.
A switch to Catalonia now looks set to go through before Monday evening's deadline as Barcelona continue to reshape their squad.
"He is in his last year of his contract. He has agreed with Barca. Maybe he will leave on Monday, but nothing is certain," Juninho told Telefoot.
"He's most likely to leave, but if he stays I hope he will help us win the matches."
Depay's arrival could speed up Ousmane Dembele's exit, with Premier League pair Liverpool and Man Utd thought to be interested.
