Morientes made his debut for Liverpool on 15 January 2005 against Manchester United, starting in a 0–1 home loss to the rivals – BBC Sport described his performance as "quiet". He scored his first goal for the club on 1 February, equalising with a 20-yard strike in a 2–1 win at Charlton Athletic, and he followed it four days later with his first goal at Anfield to open a 3–1 win over Fulham after nine minutes. He was cup-tied for the Champions League campaign, and did not feature in the victory against Milan in the final of the competition.
