The England legend has also backed him for a place in Roy Hodgson's squad for Euro 2016.
The forward was the breakout star of the last Premier League campaign as he finished as the second highest goalscorer in the division behind Manchester City's Sergio Aguero, despite it being his first year in the top-flight and only starting regularly from the end of November.
While last season was sensational for him, many are anticipating it will be much tougher this term as teams are more aware of the threat he poses, and Hurst says to do the same again would be an even greater achievement for the 22-year-old.
“What is vitally important for him this year is being able to have the same success as last season,” he told the Daily Mail.
“The top players do it, at club level, year in year out. My view is that he will do. To score 30 goals like he did, from nothing, last year, is one thing. If he does it again next year that would be, for me, a more sensational season than he's just had.”
Kane deserves an England place for Euro 2016
Apart from his stunning first season in the Premier League, Kane also managed to make a hit on the international scene, with a goal on his debut only ramping up interest and expectation around him.
He didn’t enjoy the best of times with the England Under 21s, though, as they crashed out of the European Championships limply and he failed to impress.
With Euro 2016 looming large, however, another good season could see Kane heading to the championships with the senior side, and Hurst believes he deserves his chance, saying he is a better player than many realise.
'I'd love to see him in the England side, he deserves the chance,” he added.
“If you go to a game of football and Harry Kane is playing, without knowing the teams or the players he's probably one who immediately wouldn't take your eye, until you start looking more closely. After a while it becomes clear he's a much better player than you think he is.”
