Barcelona have announced the signing of Nelson Semedo from Benfica, subject to the player passing a medical.
The right-back is expected to sign a five-year contract at Camp Nou after an initial fee of EUR30million was agreed between the clubs.
The Catalans hope to have Semedo travel with the squad next Wednesday for their pre-season tour of the United States.
Barca reportedly turned to Semedo after being rebuffed by Arsenal in their pursuit of Hector Bellerin, with a new right-back having been designated one of their priorities for next season.
The 23-year-old Portugal international is new coach Ernesto Valverde's third signing of the transfer window, following the arrivals of Gerard Deulofeu and young centre-back Marlon.
President Josep Maria Bartomeu stated this week that they hope to complete "two or three" deals before the window closes next month.
