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, Cristiano 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.
Cristiano  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. 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.
Cristiano Ronaldo  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.
Cristiano 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, Cristiano 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.  Cristiano 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.
On 5 June 2008, Sky Sports reported that 
Cristiano 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 Cristiano 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.
Cristiano Ronaldo  underwent ankle surgery at the Academic Medical  Center in Amsterdam on  7 July. He returned to action on 17 September in  United's UEFA  Champions League goalless group-stage draw with  Villarreal as a  substitute for Park Ji-Sung, and scored his first  overall 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, Cristiano 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.
Cristiano 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. 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."
