AC Milan and Liverpool kick off their UEFA Champions League campaigns at San Siro in a highly anticipated match. Milan, led by new manager Paulo Fonseca, aim to build on their first win of the Serie A season against Venezia, while Liverpool, under new boss Arne Slot, seek to recover from a shock Premier League defeat to Nottingham Forest. Key players for Milan include Rafael Leao and Christian Pulisic, with Alvaro Morata returning from rest. Liverpool will rely on Mohamed Salah and Cody Gakpo but will miss Harvey Elliott due to injury. The match holds historical significance, as the teams previously faced off in the memorable 2005 and 2007 finals. The new Champions League format will see 36 teams in a single table, each playing eight different opponents.
