De Bruyne struggled with knee problems for much of last season, limiting his impact on the club's second successive Premier League title win.
But he is fully fit and raring to go at the start of this season, as evidenced by his impressive display in the Community Shield win on Sunday.
The 28-year-old said to reporters after the game: "I'm feeling physically better than I did last year but we're not there yet.
"Sunday was the first game where almost all of the players played 90 minutes. Before we played 60."
