Ronaldo's 33 goals have come from 174 attempts - at least 67 more than any other player - giving him a shot conversion rate of 27.73, which compares to 28.26 for Ciro Immobile, who is the next highest scorer this year in Serie A with 26 for Lazio.

The Portugal international has scored 27 with his stronger right foot, four with his left and two via his head.

Robert Lewandowski, named The Best FIFA Men's Player of the Year on Thursday, has 32 Bundesliga goals for Bayern Munich since January 1, while Barcelona star Lionel Messi has just 18 in LaLiga in the same timeframe.
