In the run up to the2003–04 season,Chelsea made a series of bids for Duff,[5] with a£17 million offer, eventually triggering a release clause in the player's contract. Duff chose to move toWest London in July.[6] Signed by managerClaudio Ranieri as part of the development of Chelsea financed by new ownerRoman Abramovich, Duff made his debut in August 2003 in theChampions League against Slovakian sideMŠK Žilina. Chelsea won 2–0 and Duff was described as the "star of the show".[7] He scored his first Chelsea goal on 20 September 2003 in a 5–0 away win againstWolverhampton Wanderers. Duff scored the third Chelsea goal and was named asMan of the match.[8][9] Duff played 23 games in all competitions for Chelsea in the2003–04 season scoring five goals. He missed theChampions League semi-finals as Chelsea lost toAS Monaco but was instrumental in securing for Chelsea second place in thePremier League, the club's highest league finish for 49 years as well as being part of the Champions League run, but the season ultimately ended trophyless and with the sacking of managerClaudio Ranieri.[10][11][12]
The arrival of Dutch wingerArjen Robben and new managerJosé Mourinho posed a threat to Duff's place in the starting line-up for the2004–05 season, but an injury to Robben at the start of the season saw Duff as the only available winger. Mourinho, however, did not play Duff in the early part of the 2004–05 season, preferring a more narrow approach. Duff eventually got into the side after four games and, when Robben returned to the side, Duff's versatility saw him move to the right wing and form a wing partnership with Robben. The season proved to be successful for both Duff and Chelsea. He scored ten goals, including a crucial strike in a 4–2 win againstBarcelona in the Champions League,[13] while the team won the Premier League title by 12 points from second placed Arsenal, and theLeague Cup, in which Duff scored the winning goal in the semi-final againstManchester United.[14][15][16] He scored three goals in 28 league appearances in the following season as the club retained their Premier League title.

In the final match of the 2008–09 season, againstAston Villa in a crucial relegation decider, Duff unluckily scored the deciding own goal by deflecting in a 20-yard shot by Villa'sGareth Barry which sent Newcastle down.[23] Duff confirmed his intention to stay at the relegated club and help them back into the Premier League.[24] On 8 August 2009, Duff scored Newcastle's first goal of the2009–10 season in a 1–1 draw againstWest Bromwich Albion.[25]
