The Belgium international is ruling nothing out, with the 2014 World Cup very much in his thoughts, but concedes that he is yet to hold talks with Mourinho about where he figures in his plans.
"The most important thing for me is to play games," De Bruyne told Sky Sports News HD.
"I know that I will be stressed when I play a few games on the bench.
"I always try to give my best for the team and I've had a great season, but also next season I need to play a lot of games. With the point of the World Cup, it's very important."
Asked if he has spoken with Mourinho, the youngster added: "Not yet, but I think the time will come. The season is over now. We will see what happens."
