The 2026–27 UEFA Youth League league phase for the Champions League path will run from 8 September to 9 December 2026, featuring 36 teams competing in a single league table. Each club plays six matches (three at home, three away) against six different opponents, with the top 22 ranked teams advancing to the round of 32 of the knockout stage, where they will be joined by the ten winners of the Domestic Champions Path. Teams finishing 23rd to 36th are eliminated from the competition. The schedule mirrors the first six matchdays of the senior UEFA Champions League, with the fixture list announced on 29 August 2026, and matches played on specific dates in September, October, November, and December. In case of ties, a detailed tiebreaker system is applied, starting with goal difference and goals scored, and extending to collective opponent performance and disciplinary points. The matchdays are set for 8–10 September, 13–14 October, 20–21 October, 3–4 November, 24–25 November, and 8–9 December 2026.
