The former FC Twente star now feels comfortable at Premier League level.
"If you want to reach the top, you have to go through valleys. It's not as easy as it may seem from the outside. I can now confidently say that I've made the right choice.
"Someday, yes, I hope to return to Enschede. It is the club that has given me the best. But I can honestly say I do not regret my choice to go to Fulham," said Ruiz.
