With the 2026-27 season underway, teams across Europe's big leagues have unveiled their new prematch warmup apparel. Barcelona offers a chic Blaugrana checkerboard home variant and a purple nebula alternate inspired by their Kobe Bryant collab. Manchester United features the red rose of Lancashire on a black backdrop with multiple silhouetted graphics.

Liverpool uses the 'LFC' pattern from their away kit, textured like vintage Anfield ticket stubs from the 1970s-80s. Real Madrid implements a rosy pink and bottle green palette across all kits, with a retro prematch shirt featuring raglan sleeves, V-neck, Adidas trefoil, and 'RMCF' on the shoulders. Paris Saint-Germain creates an eye-catching neon purple melange via narrow pinstripes and swirling red-blue gradients, highlighted by an oversized central crest.

AS Roma presents a dark grey prematch jersey with a fish-scale-like checkerboard trim in carmine red and golden yellow. Inter Milan wears an all-over blue and navy triangular pattern with bright yellow logos and crests. AC Milan adorns its prematch jersey with fragments of the San Siro's iconic architecture—torn stairwells and rooflines—as spiritual mementos.

Wrexham's effort is noted but cut off in the source.
