Cristiano Ronaldo and his career in Manchester United

Ronaldo's career (2003 - 2006)

Ronaldo became Manchester United's first-ever Portuguese player when he signed for €15 million (£12.24 million) after the 2002–03 season. He requested the number 28 (his number at Sporting), as he did not want the pressure of living up to the expectation linked to the number 7 shirt, which had previously been worn by players such as George Best, Bryan Robson, Eric Cantona, and David Beckham.

"After I joined, the manager asked me what number I'd like. I said 28. But Ferguson said 'No, you're going to have No. 7,' and the famous shirt was an extra source of motivation. I was forced to live up to such an honour."

Ronaldo made his team debut as a 60th-minute substitute in a 4–0 home victory over Bolton Wanderers. He scored his first goal for Manchester United with a free kick in a 3–0 win over Portsmouth on 1 November 2003. Ronaldo ended his first season in English football by scoring the opening goal in United's 3–0 FA Cup final victory over Millwall.

He scored United's 1000th Premier League goal on 29 October 2005 in a 4–1 loss to Middlesbrough. He scored ten goals in all competitions, and fans voted him to his first FIFPro Special Young Player of the Year award in 2005.

He was sent off in the Manchester derby at the City of Manchester Stadium on 14 January 2006 (a game which United lost 3–1) for kicking City's former United player Andrew Cole.

Ronaldo won his second trophy in English football in the 2005–06 season, scoring the third goal in Manchester United's 4–0 Football League Cup final victory over Wigan Athletic.

Ronaldo's career (2006 - 2009)

The 2006–2007 season proved to be the breakout year for Ronaldo, as he broke the 20 goal barrier for the first time and picked up his first league title with Manchester United.

In November and December 2006, Ronaldo received consecutive Barclays Player of the Month honours, becoming only the third player in Premier League history to do so after Dennis Bergkamp in 1997 and Robbie Fowler in 1996. He scored his 50th Manchester United goal against city rivals Manchester City on 5 May 2007 as United claimed their first Premier League title in four years, and he was voted into his second consecutive FIFPro Special Young Player of the Year award at the end of the year.

Despite rumours circulating in March 2007 that Real Madrid were willing to pay an unprecedented €80 million (£54 million) for Ronaldo, he signed a five-year, £120,000-a-week (£31 million total) extension with United on 13 April, making him the highest-paid player in team history.

Ronaldo amassed a host of personal awards for the season. He won the PFA Players' Player of the Year and PFA Young Player of the Year awards, joining Andy Gray (in 1977) as the only players to receive this honour. In April, he completed the treble by winning the PFA Fans' Player of the Year. He also won the PFA Fans' Player of the Year and the FWA Footballer of the Year, becoming the first player to win all four main PFA and FWA awards. Ronaldo was also one of eight Manchester United players named in the 2006–07 PFA Premier League Team of the Year.

Ronaldo's 2007–08 season began with a red card for a headbutt on Portsmouth player Richard Hughes during United's second match of the season, for which he was punished with a three-match ban. Ronaldo said he had "learned a lot" from the experience and would not let players "provoke" him in the future. After scoring the only goal in a Champions League away match against Sporting, Ronaldo also scored the injury-time winner in the return fixture as Manchester United topped their Champions League group.

He finished as the runner-up to Kaká for the 2007 Ballon d'Or, and was third in the running for the FIFA World Player of the Year award, behind Kaká and Lionel Messi.

Ronaldo scored his first hat trick for Manchester United in a 6–0 win against Newcastle United at Old Trafford on 12 January 2008, bringing Manchester United up to the top of the Premier League table. He scored his twenty-third league goal of the season in a 2–0 win against Reading, equalling his entire total for the 2006–07 season. During a 1–1 Champions League first knockout round draw against Lyon on 20 February, an unidentified Lyon supporter continuously aimed a green laser at Ronaldo and United teammate Nani, prompting an investigation by UEFA. One month later, Lyon were fined CHF5,000 (£2,427) for the incident.

On 19 March 2008, Ronaldo captained United for the first time in his career in a home win over Bolton, scoring both goals in the 2–0 victory. The second of the goals was his 33rd of the campaign, which set a new club single-season scoring record by a midfielder and thus topped George Best's forty-year-old total of 32 goals in the 1967–68 season. Ronaldo scored another brace in a 4–0 win over Aston Villa on 29 March, which at the time gave him 35 goals in 37 domestic and European matches as both a starter and substitute. Ronaldo's scoring streak was rewarded with his becoming the first winger to win the 2007–08 European Golden Shoe, finishing eight points ahead of Mallorca's Dani Güiza.

In the 2007–08 Champions League final on 21 May against league rivals Chelsea, Ronaldo scored the opening goal after 26 minutes, which was negated by a Chelsea equaliser in the 45th minute as the match ended 1–1 after extra time. His misfire in the penalty shoot-out put Chelsea in position to win the trophy, but John Terry shot wide right after slipping on the pitch surface, and Manchester United emerged victorious 6–5 on penalties. Ronaldo was named the UEFA Fans' Man of the Match, and wrapped up the campaign with a career-high 42 goals in all competitions, falling four short of Denis Law's team-record mark of 46 in the 1963–64 season. In the Champions League he was also named best forward and player of the tournament and was the competition's top goalscorer.

On 5 June 2008, Sky Sports reported that Ronaldo had expressed an interest in moving to Real Madrid if they offered him the same amount of money the team had allegedly promised him earlier in the year. Manchester United filed a tampering complaint with FIFA on 9 June over Madrid's alleged pursuit of Ronaldo, but FIFA declined to take any action. Speculation that a transfer would happen continued until 6 August, when Ronaldo confirmed that he would stay at United for at least another year.

Ronaldo underwent ankle surgery at the Academic Medical Center in Amsterdam on 7 July. He returned to action on 17 September in United's goalless UEFA Champions League group stage draw with Villarreal as a substitute for Park Ji-Sung, and scored his first goal of the season in a 3–1 League Cup third round win over Middlesbrough on 24 September.

In a 5–0 win over Stoke City on 15 November 2008, Ronaldo scored his 100th and 101st goals in all competitions for Manchester United, both from free kicks. The goals also meant that Ronaldo had now scored against each of the other 19 teams in the Premier League at the time. On 2 December, Ronaldo became Manchester United's first Ballon d'Or recipient since George Best in 1968. He finished with 446 points, 165 ahead of runner-up Lionel Messi. He was awarded the Silver Ball after finishing with two goals as United won the Club World Cup on 19 December.

On 8 January 2009, Ronaldo was uninjured in a single-car accident in which he wrote off his Ferrari 599 GTB Fiorano in a tunnel along the A538 near Manchester Airport. A breathalyser test he gave to police officers at the scene was negative, and he attended training later that morning. Four days later, he became the first Premier League player ever to be named the FIFA World Player of the Year, in addition to being the first Portuguese player to win the award since Luís Figo in 2001.

Ronaldo scored his first Champions League goal of the season, and first since the final against Chelsea, in a 2–0 victory over Internazionale that sent United into the quarter-finals. In the second leg against Porto, Ronaldo scored a 40-yard game-winning goal as United advanced to the semi-finals. For this goal Ronaldo holds the distinction of being the first player to win the FIFA Puskás Award, in 2009, an honour handed by FIFA to the best goal of the year. He later called it the best goal he had ever scored. Ronaldo participated in his second consecutive Champions League final, but made little impact in United's 2–0 loss to Barcelona. He finished with 53 appearances in all competitions, which was four higher than the previous year, but scored sixteen fewer goals (26) than his career-best total of 42 from the previous season.

On 11 June, Manchester United accepted an unconditional offer of £80 million from Real Madrid for Ronaldo after it was revealed that he again had expressed his desire to leave the club. It was confirmed by a representative of the Glazer family that the sale was fully condoned by Ferguson. When Ronaldo had eventually completed his transfer to Real, he expressed his gratitude towards Ferguson for helping him develop as a player, saying, "He's been my father in sport, one of the most important factors and most influential in my career."
