Barcelona 2011 — Qatar Airways / Nike Blaugrana

Barcelona's Nike home kit from 2010–11 — the season they won La Liga and reached the Champions League Final (losing to Manchester United) — was the definitive Blaugrana design of the modern era. The deep blue and maroon vertical stripes, the Qatar Foundation sponsorship (the club's first shirt sponsor in 110 years, generating significant debate), and its association with Messi, Xavi, Iniesta, Villa, and the peak tiki-taka side make it the most collectible Barcelona shirt in the club's history.
