The 22-year-old has not started a Premier League match since August and has been linked with a short-term return to the Bundesliga, where he excelled last season for Werder Bremen.
"To be honest, I haven't thought about it yet," De Bruyne told Het Laatste Nieuws. "I know something has to change. Sooner or later, I will have to play.
"But what can I do at this moment besides training hard and keeping quiet? I feel really strong at this time - I think I have never been this fit before. I got a lot of support of family and friends who visit me over here.
"My team-mates have been fantastic. You know, I haven't worried much about my situation. My career has always gone up, but then it's sometimes normal it makes a horizontal line."
De Bruyne, who joined the Blues from Racing Genk in 2012, has also been linked with a move to Juventus.
