Cristiano Ronaldo scored 31 goals for Manchester United in the 2007–08 Premier League season. He reached that total in 34 league appearances and won the Premier League Golden Boot.
The season marked Ronaldo's transformation from a spectacular winger into a consistently prolific scorer. He scored in a range of ways, including powerful runs, long-range strikes, free kicks, and headers. His 31 league goals helped United win the title, while his goals in other competitions took his overall season total to 42.
Ronaldo's 31 goals equalled the Premier League record for a 38-match season, previously set by Alan Shearer for Blackburn Rovers in 1995–96. Because the Premier League had moved to a 38-game schedule, comparisons with earlier seasons can be misleading. Another frequent mix-up is confusing Ronaldo's 31 league goals with his 42 goals in all competitions. He also scored 18 Premier League goals the following season, when United won the title again.
