Alianza Lima created a remarkable upset in the Copa Libertadores preliminary round, eliminating Argentine giants Boca Juniors despite being forced to wear last season's training shirts due to a kit clash.

Alianza Lima 2025 Home & Away Kits Too Similar to Boca Home Kit - Team Wears 2024 Training Shirt

The Peruvian side had to improvise its matchday attire when faced with Boca's traditional blue and yellow home strip. With Nike having provided Alianza a blue-dominated home kit and an entirely blue away kit for the current season, the team was left without a suitable option to prevent confusion against Boca's colors. Alianza Lima's solution was to utilize white training shirts from last season, which featured only minimal blue detailing on the collar.
Alianza Lima added a Peruvian flag as well as all match sponsors to the training shirt.
Alianza Lima will next face Chilean side Deportes Iquique in the third qualifying round, potentially creating another uniform challenge as Iquique also wears blue kits, albeit in a lighter shade.
