Despite scoring on his debut against Villarreal, the Welsh winger has struggled in the early days with life at the Bernabeu.
The pair are expected to play in Wednesday night's encounter with Italian champions Juventus, and Ronaldo is understanding of the difficulties that have faced Bale in his early career in Spain.
"I think Gareth Bale has done well,” Ronaldo said on ESPN. “Since he arrived he has had to do a pre-season, so it has been difficult for him. But you can see he is very excited about being here.
The former Ballon d'Or winner also sympathised with the former Tottenham midfielder for the pressure that is put on him.
Moving for £85million was always going to leave Bale with a degree of pressure, however, Ronaldo believes focus should be shifted to other members of Carlo Ancelotti's squad.
"People put pressure on him, for how much he costs, which I do not think is good for him," he said. "If you want to help him, leave him alone, put pressure on other players. I am sure he will do very well for the team.”
Some sections of the media have questioned whether the pair can play together, with their similar playing styles.
However, Ronaldo says the pair must learn to play with each other, and dismissed any notion that the Welshman copied his trademark free-kick style:
“All good players can play together, and they must, to make the team good,” he said. “I do not feel Bale has copied me with his free kicks -- he has his own style of taking them. If he asks for advice of course I will give it.
“He is a very humble kid, who I would like to help if he asks. I see him as a great player, and want to play with the great players, to win important things.”
Having started the season in less than spectactular fashion, Madrid now have to huge clashes to kick-start their season.
After taking on Juventus at the Bernabeu on Wednesday, Real Madrid face Barcelona at the Nou Camp on Saturday.
