Kewell made his debut for Liverpool in the opening game of the 2003–04 Premier League season, a 2–1 home loss to Chelsea on 17 August 2003. Kewell scored his first ever goal for Liverpool in a 3–0 away win over great rivals Everton in the Merseyside derby with a great first time strike. Kewell completed his first ever season at Anfield equal second with Emile Heskey by scoring seven goals, nine behind Michael Owen as Liverpool's top goalscorer for the 2003–04 Premier League season. Kewell also finished as Liverpool's top scorer in the 2003–04 UEFA Cup, scoring goals against Olimpija Ljubljana, Steaua București and Levski Sofia which ended Kewell's season total of ten goals. Kewell kicked off his 2004–05 season poorly, failing to score in his first 14 matches, due to injury problems. He did finally score his first goal in round 15 of the Premier League in a 1–1 away draw against Aston Villa, and that was his only Premier League goal of the season, making this one of his worst seasons ever. Kewell started and played in the 2005 League Cup final and the 2005 Champions League final.
