Ferran Torres is clear to make his Barcelona debut in Wednesday's Supercopa de Espana semifinal against Real Madrid on Wednesday night.
Torres joined the club from Manchester City for around 65 million euros and could only be registered after Samuel Umtiti took a wage cut in his new contract.
The original plan was to sell the French defender but he was reluctant to leave the Nou Camp and opted instead to reduce his wages to stay in Spain.
The 21-year-old will wear the No.19 and could make his first appearance against Real Madrid in the first semi-final in Saudi Arabia.
He has been impressing new coach Xavi Hernandez in training but until now has been resigned to just minutes on the practice field.
