Why is Luis Diaz not playing today for Bayern Munich vs Atletico Madrid in 2026-27 UEFA Champions League Matchday 4?

Luis Diaz will miss Bayern Munich’s Champions League trip to Atletico Madrid with a hamstring injury, as the German side travels with only 19 players available. Bayern Munich arrive in Madrid for one of the biggest games of Matchday 4 of the 2026-27 Champions League , but not at full strength. One of the names missing from the squad is a player who had been among the team’s most influential attackers in recent weeks, and his absence adds another challenge for coach Vincent Kompany.
