De Bruyne was a hot prospect with the Blues, especially after a successful loan spell with Werder Bremen.
His spell at the German club got the attention of Manchester City, and the rest is history.
"Wolfsburg was different because I just wanted a new challenge and not be loaned out because that system is really tough for people," he said on BT Sport's 'What I Wore' show.
"They don't always understand – when you do a few loan spells and come back to the team you know people are still doubting, saying 'he's a young player, is he going to make it.'
"In my mind I had played four years in Belgium, a year in Germany, had 160-180 games under my belt plus national team experience, so you're not thinking like a young boy at 18 anymore who is just happy to get a game.
