In the 2002–03 season, Baroš scored twice on his Premiership debut away to Bolton Wanderers on 14 September 2002, as Liverpool won 3–2 away. Baroš was a substitute in the 2003 Football League Cup Final against Manchester United. He entered the game in the second half, but did not play to the end of the game, being substituted himself a minute before the end of the game. Liverpool won the game 2–0 to win the cup, the first major trophy of Baroš' career. Towards the end of the season, he scored twice in a 6–0 away win over already-relegated West Bromwich Albion in April 2003. He ended his first season in the Premiership with 12 goals for the club.
