This official Lazio home jersey for the 2003/2004 season was made by Puma and sponsored by Parmacotto. The Lazio blue color is enhanced by white inserts along the sides and shoulders, giving it a modern and dynamic look. The Lazio crest is on the left chest, with the Puma logo on the right, and Parmacotto branding prominently displayed in yellow and black in the center. The back features the name "Mihajlovic" and number 11, paying tribute to Serbian defender Sinisa Mihajlovic, known for his powerful free kicks and leadership on the field.
During the 2003/2004 season, Sinisa Mihajlovic was a cornerstone of Lazio's defense and played a key role in their Coppa Italia victory. His free-kick prowess made him a formidable threat to opposing goalkeepers and a fan favorite at Lazio. Under Roberto Mancini's management, Lazio had a strong season in both Serie A and domestic competitions.
