The oil-rich Citizens have become regulars in the Champions League since they were bought out in 2008, but Robben feels that there is more to City's success than just having money.
"They are not the only club with a lot of money in Europe," Robben is quoted as saying to Sky Sports News.
"You can't just buy quality; you have to build a team. Having enough good players will give you a chance of hitting the jackpot at some point.
"They have the potential to progress well [in the Champions League] this time."
