Speaking to Belgian publication HLN, De Bruyne said: "For Michele, an exotic adventure is okay. These are also conversations that we are increasingly having as a family.
"I still have one year left on my contract, so I have to think about what could happen. My eldest is now eight years old and knows nothing but England. He also asks how long I will play for City. Once the moment comes, we will have to deal with it in a certain way."
Pressed on the possibility of entertaining the Saudi Pro League's interest in his services, De Bruyne added: "At my age you have to be open to everything. You're talking about incredible amounts of money in what may be the end of my career. Sometimes you have to think about that.
"If I play there for two years, I will be able to earn an incredible amount of money. Before that, I had to play football for 15 years. I may not even reach that amount yet. Then you have to think about what that could mean next. But at the moment I haven't had to think about that yet.”
