Comparisons between the pair have intensified over recent weeks as Spurs lock horns with the reigning kings of Europe in the Champions League.
Ronaldo was on target during a 1-1 draw at the Santiago Bernabeu, and he and Kane will be going in search of more goals at Wembley on Wednesday.
It has been suggested ahead of the clash that Tottenham now boast a forward to rival Real’s free-scoring icon, but Ginola feels it is still too early to place Kane in that bracket.
He told talkSPORT on the 24-year-old double Premier League Golden Boot winner: “You can’t compare Harry Kane to Ronaldo...yet.
“Even the qualities are not the same. Ronaldo is about pace – I’m not saying that Harry Kane is slow, but he’s not the same kind of player.”
Among those to have talked up Kane’s qualities is Spurs team-mate Jan Vertonghen , with the Belgian defender telling reporters: “Harry for me is one of the best No 9s in Europe, maybe the best. He shows that every week and I wouldn't swap Harry for any player at the moment."
Steffen Freund, meanwhile, has billed the England striker as a natural “successor” to Ronaldo , amid ongoing talk of interest from Madrid .
Ginola understands such praise, but he still considers the Portuguese four-time Ballon d’Or winner to be in a class of his own at present.
The ex-Spurs winger added: “You could swap Harry Kane for Ronaldo, obviously, because Ronaldo will do some great stuff for Spurs and Harry Kane will do the same for Real Madrid.
“But, on the other hand, Ronaldo has done so much for the game and he works so hard. All the credit to him because for the last five or six years, even more than that, since he played football, every year he is sending the right message to youngsters – if you want to stay at the top, you need to work really hard.”
Kane has bettered Ronaldo’s goal return so far this season, with the Tottenham frontman having netted 13 times in just 12 appearances, compared to a return of seven in 11 from a man recently awarded the top prize at FIFA’s Best awards.
