The Dane, who faces a Tottenham side on Sunday that will be without the Real Madrid-bound Welshman, believes the 24-year-old is a level below the Portugal international
The Tottenham winger is on the verge of sealing a world-record transfer to Real Madrid after the Liga giant tabled a bid worth around 100 million euros.
However, Swansea manager Laudrup, who played at the Santiago Bernabeu for two years in the 1990s, feels Bale is not yet in the same bracket as Ronaldo or Barcelona star Lionel Messi.
"You have to admit Gareth Bale was a superstar for Tottenham last season," said the Dane.
"Even when you have a good team it is always so nice that there is one player, like Bale, who you can give the ball to and he will do something great.
"When you see Real Madrid play they are very good players but at certain points they have Ronaldo, and Barcelona have Messi.
"For me, over the last four or five years those two have been at a level by themselves.
"Then you have 10 or 12 players just below that and Bale is definitely there with [Andres] Iniesta, [Sergio] Aguero and Robin van Persie."
