FC Barcelona has announced a groundbreaking multi-year partnership with Nike, touted as the most lucrative sponsorship deal in football history, valued at approximately €1.7 billion over 14 years. This agreement, effective this season, solidifies Nike's role as the club's primary technical supplier across all teams and aims to enhance global retail and licensing operations. The partnership marks a significant turnaround after previous tensions between the two parties, as Barcelona considered alternative kit suppliers due to financial struggles. Club president Joan Laporta noted that this new collaboration is designed to stabilize the club's finances and align with LaLiga's spending regulations. Although exact financial figures remain undisclosed, reports suggest the deal could generate over €100 million annually. This partnership, which began in 1998, has previously seen Barcelona achieve notable success on the field, including multiple Champions League titles.
