"The team is really balanced but if Bale comes he would be another plus, which is never a bad thing," Isco told the official Madrid website.
"He’s a great player. I think we already have a solid team, but he would be a good reinforcement."
The attacking midfielder then went on to voice his satisfaction with the way he has adapted to life at the Santiago Bernabeu following his €30m (£25m) move this summer.
"Everything’s been going really well. I adapted fairly quickly and my team-mates have helped me loads," he added. "There’s a really good vibe and we have to keep it that way."
