Indeed, the previous quintuple hat-trick scorers were in the 1930s - George Hunt in 1933-34 and Johnny Morrison in 1936-37.
Harry joined that list with four trebles in the Premier League - West Brom and Stoke at the Lane, Leicester and Hull away - and tne in the FA Cup at Fulham.
His final two hat-tricks in the final two games of the season at Leicester and Hull helped secure the Premier League's Golden Boot for the second-successive season.
Harry is now up to eight hat-tricks for Spurs, only the great Jimmy Greaves (15), Bobby Smith (12), George Hunt (11), Johnny Morrison (10) and Cliff Jones (10) have scored more.
