This is an authentic Reebok football jersey from Sporting Clube de Portugal's 2002–2003 season, worn by Cristiano Ronaldo during his debut professional season. The back features 'C. RONALDO' and large number '28' in bold black with white outline, positioned below the sponsor 'BANCO ESPIRITO SANTO'. The jersey showcases Sporting CP’s iconic vertical green-and-white stripes (here rendered as dark green/black and white), with Reebok branding subtly placed beneath the numerals. Sleeve details include the Portuguese Primeira Liga patch on the right sleeve and a club crest patch on the left. Made from lightweight, breathable polyester fabric typical of early-2000s performance kits, it offers vintage authenticity and collector value. Ideal for football memorabilia enthusiasts, retro sportswear fans, or casual streetwear styling with a nostalgic edge. The clean design balances heritage aesthetics with modern display appeal—perfect for framing, gameday wear, or layered under outerwear.
