Kane's first-half double at Huddersfield on Saturday brought his career total to 84 Premier League strikes.
Ronaldo reached 84 goals in six seasons at Manchester United, playing 196 games in that time. Kane, on the other hand, is barely into his fourth full season with Spurs and needed just 123 games.
The 24-year-old now has 27 Premier League goals in 2017 so far – the most by any player, and his 13 goals in September make it the best month of his career.

The goals against newly-promoted Huddersfield also continued Kane's record of scoring against every team he's faced in the Premier League but one - Cardiff City are the exception despite playing them twice.
Tottenham would go on to win the match 4-0 at Kirklees Stadium.
