Despite his relegation to the bench, Abbiati still managed to contribute to Milan's Coppa Italia and Champions League victories that season. He appeared in Milan's 2003 Supercoppa Italiana defeat to Juventus on penalties, but Dida later regained his position as starting goalkeeper. Abbiati played one minute in Milan's 2004–05 Champions League campaign, when he came on as a substitute in the 74th minute after Dida had been struck by a flare thrown from the crowd during the quarter-final second leg against cross-city rivals Internazionale on 12 April 2005. The match was ultimately suspended less than a minute later. His last match in a Milan kit came on 20 May in a 3–3 home draw with Palermo, a match which saw the starters rested for the upcoming Champions League final, which Milan lost to Liverpool after squandering a 3–0 half-time lead. Milan finished second in Serie A that season.
