The 2002–03 season was the 123rd season of competitive football in England.
Key: ECQ = 2004 European Championship qualifiers, F = Friendly; scores are written England first
Manchester United, unbeaten in the league after 22 December, overhauled Arsenal during the final three months of the season to clinch their eighth Premiership title in 11 seasons, while the other two Champions League places went to Newcastle United and Chelsea. Going into the UEFA Cup were Liverpool (who made an excellent start to the league, going unbeaten in their first three months before a sudden collapse) and Blackburn Rovers, along with FA Cup runners-up Southampton (who also achieved their best Premiership finish of 8th place) and Fair Play award winners Manchester City (who finished an impressive ninth on their Premiership comeback). Southampton had not played in European competitions for nearly 20 years, while Manchester City's last European campaign was a quarter of a century ago.
Everton finished seventh in their first full season under the management of David Moyes, the club's highest finish for seven years, in a campaign where the club was the centre of national media and public attention following the performances of 17-year-old striker Wayne Rooney, who became the youngest full England international after the season's end.
Compensation for Arsenal after their spectacular failure to retain the league title came in the form of retaining the FA Cup - the first side to do so for 21 years.
Leeds United's season was plagued by a loss of form and mounting debts, and having to sell several key players, as they slipped to 15th place - their lowest finish for 10 years and a stark contrast to the previous five campaigns, where they had never finished outside the top five. Manager Terry Venables was axed towards the end of March after eight months in charge, with Peter Reid taking over for the final weeks of the season to secure survival and earn himself a permanent contract. Aston Villa's 16th-place finish was their lowest for eight years, although their strong home form ensured their survival in the Premier League.
Sunderland's season started badly and got worse as they finished with a record Premiership low of 4 wins, 19 points and 21 goals, losing their final 15 league games in the process. The Wearside club went through three managers, with Peter Reid (one of the league's longest-serving managers) leaving in early October to be replaced by Howard Wilkinson, who lasted just five months before Mick McCarthy was appointed. They were joined by West Bromwich Albion, who attained just 26 points in their first top flight season for nearly 20 years and won just three times in the league after September. Last to go down were West Ham United, who went down with 42 points - the highest points tally of any club to be relegated from the Premiership under the 20-club format.
