The former Spurs legend has called the Wales international "awesome" and believes the 23-year-old winger will be in the same class as the Barcelona and Real Madrid superstars
The former Spurs wide man believes the 23-year-old Welshman has the tools to take him to the same level of the world's finest footballers.
However the Frenchman has also warned Tottenham that they will find it very hard to keep hold of the 2010-11 PFA Players' Player of the Year, and that it is just a matter of time before he moves on to a bigger club.
"I don’t know if he is [at the same high level as Messi and Ronaldo]. He has to play more in the Champions League and competitions like that. But there’s no doubt the kid is brilliant," Ginola told talkSPORT.
"He is awesome. I've seen him play so many times and he can make the difference. He has got the pace, he has got the strength, he has got the vision. He has got everything to be at the top alongside players like Messi and Ronaldo.
"At the moment the club is trying to find a way to play better football and Gareth Bale is probably the key. But he can't play on his own, he has to rely on other players in the team.
"It will be complicated this season and it will complicated as well for the club to keep a player like Gareth Bale for some years."
