Following Desailly's retirement, new Chelsea manager José Mourinho chose Terry as his club captain, a choice which was vindicated throughout the 2004–05 season as Chelsea won the Premier League title in record-breaking fashion with the best defensive record in Football League history with the most clean sheets and the most points accrued.
He was voted Player of the Year by his fellow professionals in England and scored eight goals, including a late winner against Barcelona, in the UEFA Champions League.
He was voted the best defender in the Champions League for the season.
In September 2005, he was selected as a member of the World XI at the FIFPro awards.
The team was chosen by a vote of professional footballers based in 40 countries.

Chelsea defended their Premier League title in 2005–06, earning 91 points, and confirming the title with a 3–0 victory against Manchester United.

In a match on 14 October 2006 against Reading, Terry had to take over in goal for Chelsea in the final minutes of the match after goalkeepers Petr Čech and Carlo Cudicini were injured and Chelsea had no substitutes remaining.
Terry kept a clean sheet as Chelsea held out to win 1–0.
On 5 November 2006, playing against Tottenham Hotspur, Terry was sent off for the first time in his Chelsea career after receiving two yellow cards as the Blues lost at White Hart Lane for the first time since 1987.
Terry was charged with misconduct by the FA for questioning the integrity of match referee Graham Poll after the match.
On 10 January 2007, Terry was ordered to pay £10,000 for the inappropriate conduct after he changed his mind and pleaded guilty to the FA.

In the 2006–07 season, Terry missed matches for Chelsea due to a recurring back problem.
On 26 December 2006, José Mourinho stated that his captain might require surgery to fix the problem.
In Terry's absence Chelsea drew 2–2 at home to both Reading and Fulham over Christmas, draws that were to prove crucial in the destiny of the Premier League title for that season.
On 28 December, Chelsea released a press statement saying Terry had had back surgery: "The operation to remove a sequestrated lumbar intervertebral disc was successful."
Although he was expected to return in the match against Wigan Athletic, which Chelsea won 3–2 thanks to a late goal from winger Arjen Robben, Terry was missing once again, due to the recurring back problem.
He made his return in Chelsea's 1–0 victory over Charlton Athletic on 3 February 2007 coming on in the 88th minute for Claude Makelele.
Terry played his first 90 minutes of football for nearly three months in Chelsea's 3–0 victory over Middlesbrough and received much applause from the Chelsea faithful.
Didier Drogba scored two goals for Chelsea in that match, while the other goal came courtesy of an own goal from Abel Xavier of Middlesbrough.

Playing in the UEFA Champions League round of 16 away against Porto, he suffered another injury, this time to his ankle, and was set to miss the 2007 League Cup Final against Arsenal, but managed to recover from the injury within days and played in the final.
During the second half of the match, at an attacking corner, he threw himself at the ball with a diving header; Arsenal's Abou Diaby, in an attempt to clear the ball, kicked Terry in the face.
Terry was unconscious for several minutes, at which point he nearly swallowed his tongue.
He was carried off the field on a stretcher and immediately transferred to the University Hospital of Wales.
Terry discharged himself the same day and returned to the Millennium Stadium to celebrate his team's 2–1 win.
The only recollection he had of the second half is walking out onto the pitch and he did not remember the ten minutes he played prior to his injury.
He went on to lead Chelsea to the semi-final of the UEFA Champions League, the third time in four years that Chelsea had made it to the final four of the competition.
In May 2007, Terry captained Chelsea in the 2007 FA Cup Final, in the first FA Cup final at the new Wembley Stadium.
